    This has turned into a whole vehicle build thread now and not just an engine swap. So I have logged work I have done on the rig, issues, solutions and links to other resources, as well as my parts costs, etc.

    From May 2008 to Dec 2012 (when the 2F died), usage activities for this rig have been: for DD, a couple trips to Canyonlands Utah, camping up in the mountains and the like.
    Hauling stuff and for the ride. Love a manual tranny

    FUTURE uses (once I get it back together again - is that possible?): Longer trips in the western US background, mostly Utah

    Since I am an old software geek (same age as Bill Gates, but much poorer) and engineer things, I have planned the project, researched it and then modified it over time as reality comes between the eyes or new options come to light. So I might have too much detail, but this is my thread. Deal with it.

    Suggestions and criticisms are welcome to be considered. (And I have considered many and changed my plan several times from such)

    I acquired the rig in May 2008 for $2500. 189,000 miles on it.
    I put 49,000 miles on it until the engine went out, Dec 2012 (seen later on this thread)

    After buying it, it Immediately needed:

    2F Specific mods/fixes (things that no longer apply since the 2F is now GONE):
    New clutch pressure plate, disc, throwout bear, etc
    New oil (old oil was very lumpy) and filter, changed again in 500 miles for flushing of bad oil
    New coolant (Moab Red did NOT seem right color for coolant) after a BIG flush
    (those last 2 items and others hints, indicated to me that PO's did NOT take care of the rig.
    I believe that is why the engine block later died at 238k miles)
    New coolant hoses throughout

    Body specific mods/fixes that outlast the 2F engine = they are still on the rig:

    rear pinon bearing broke, and replaced
    Had rear axle rebuilt with new bearings and seals (from Kurt at
    Front pinon bearing replace
    New OME shocks
    New steering stablizer

    Over the next several years I did or bought the following:

    2F Specific mods/fixes (things that no longer apply since the 2F is now GONE):

    New water pump.
    New thermostat and gaskets
    new vac lines
    Removed air pump and installed JimC's idler pulley
    JimC Dizzy rework a used 2nd dizzy I sent him.
    Bought a 2nd head, had it rebuilt with SS valves (as per JimC's counsel), oil galley, rocker arm serviced and swapped in on a saturday
    6-to-1 header
    New muffler
    Trollhole carb (bought a second for a spare)
    Radiator shroud 2 piece mod

    Body/frame specific mods/fixes that outlast the engine:

    New aftermarket radiator.
    OME EMU Lift
    Saginaw PS installed
    New Clutch MC and Slave
    Painted the top of the hood - it REALLY needed it, as it was peeling
    Refreshed the Herculiner that some PO put on the sides.
    Steering gear box reworked at Texas Steering
    New rebuilt brake booster
    New brake MC and flush
    New pads in front and brakes in rear
    200 Amp Mean Green Alternator
    Fixed driver footwell rust rot
    Cruiser C-r-a-p installed on floor, got quieter
    ARB Rear Air-Locker
    Install FJ62 4.11 third members, front and rear
    Cleaned up rear cargo area, rear seat, and new rear cargo carpet
    Fab'ed my new headlight harness (now have 14.4 volts at lights instead of 8.6v)
    Fog lights
    Off road lights on roof
    Improved electrical system, better wires, grounding, etc.
    Had front knuckles rebuilt, new bearings and seals
    Added to the A pillar, a 4 gauge strip. Physical Water temp gauge, Vac gauge, Fuel mixture. Future Oil pressure
    Installed HAM radio

    Bunch of other stuff which I forget what I did.

    As can be seen, I didn't know much about Cruisers back then because of how much repair I had to do it BUT.....

    I view that as ALL TUITION well spent for my education of LandCruisers

    Then I lost the 2F, I sold all the "good" rebuilt/new parts from that engine to help fund the SBC

    While it is down, I miss it terribly. BUT I am having fun rebuilding it. Not too fancy car looks,
    but to utilitarian function - I drive through A LOT of scrub oak, which scratched the old paint job something terrible, so I extended the old Herculiner from 1/3 the way up to all the way up to the windows. It protects so much better.

    I want a off road 4x4 truck that can take the work, and keep running for some time.

    **************************************** Original post *************************

    Ok, it is time to ask some questions on a 350 swap for my fj60.

    I have been researching building my own engine from a donor block for some time. I have wanted to do this since I was a teenager, and I am NOT getting younger. So I have been: Reading, asking and calculating.

    I am starting with a 1983 chev truck 4-bolt main block, of which I will reuse the block and the Quadrajet carb (which I am rebuilding). Everything else will be bought new. My first choice is a 383 with 4.040 bore (block is already at 4.030). Then my second choice is just the 350 at 4.040 bore.

    My goal is to build a torquer with good low to mid torgue and low RPM target. I don't want to run the rig above 85 (lol). I have also purchased the Dyno Sim5 computer program to compare different configurations. This will go into my FJ60 with a NV4500 tranny, NP241 TC and a 14 bolt rear diff, all like lehiguy's rig.

    I am choosing the following parts:

    new version of GM Bowtie Vortec heads, small runners
    Edelbrock Vortec spread bore intake
    roller cam CompCams x4270HR (220/224 @.050) 111LSA .474 lift

    The Sim5 gives the following - one for the 383 and one for the 350 - numbers:

    TQ 493 @ 2500 sea level (403 @ 2500 5500ft)
    HP 383 @ 5000 sea level (313 @ 5000 5500ft)

    TQ 522 @ 2000 sea level (426 @ 2000 5500 ft)
    HP 373 @ 4500 sea level (304 @ 4500 5500 ft)

    Given these are just sims, they do provide relative comparisons.

    So my question becomes: How much torque is too much for a FJ60?

    Pics below is the dirty block in the back of the 60 on the way to the machinist. My plan is to have it worked over the next 4-5 months (Scott at Provo Utah's Charlies, will work on it in idle time and I will pay over that duration).

    UPDATE: It took 12 months

    thought to at least post a pic of the rig itself. The hood is the first part to be cleaned up and painted. Other portions will be painted - rear hatch is in process.

    it's not HP or torque we're super concerned with, it's "shock" or "impact" loads. if the wheels ( front or rear ) loose traction and then hook up again, you can and will break stuff. like drivelines, u-joints, pinions, axle shafts,......but even that's not so common.
    the components in your cruiser can put up with the powerplant you plan on running them with just fine. it's not like you'll be floored at all times, and i doubt you'll be seeing more than 3k RPMs a whole lot.

    fwiw, i built a 60 with a supercharged vortec 5.3 for a customer and fellow mudder. it's been on the road ( and offraod ) for a while now with no issues.

    let your brain make the decisions, not your right foot.

    I would go for the most torque you can make and run on regular pump gas, and that would get you to the 383 setup I'm sure. High torque at low rpm is the best route for trucks/offroad in my view. I don't think there are that many intake solutions with using the vortec heads and I assume the intake you are referring to is a dual plane type. The vortec heads have a different bolt pattern where the intake bolts down to the cylinder heads than the older conventional 5.7 heads. The Dart II iron eagle heads are a good alternative if you were considering other options.

    That has been my base thought, which why I studied the 383 type of engine. As for the intake, it is an Edelbrock Performer for spreadbore

    The cheaper base unit is at

    The more shiny one is at Edelbrock 21161 Edelbrock Performer Intake Manifolds for Chevy

    The original Vortec heads are a great head set and I have studied their characteristics. GMPP has come out an after market Vortec head that addresses some of the short coming of the original, thicker deck, improved exhaust, takes upto .530 valve lift, better springs. For an iron head, the GM engineers has done a great job. One can get an original Vortec head from for around $400 that has good valve lift, but these new GM heads can be had for $520 vis Jegs.

    Thanks for pointers

    Exactly, I wasn't trying to reach high numbers. I just studied and put together components that leaned toward low end torque instead of high end HP (high end HP is what all the books stress on building up a SBC, mag articles as well). After I had my build plan laid out, that is when I bought the software sim to plug in things and see what came out (also I found that every person I asked had different opinions on things and had no "normalized" foundation to start with).

    Then I put the numbers in the Sim and I saw bigger numbers than I expected with TQ. That lead to posting this question due to the "breakage" factor as you mentioned. I started with the 383 and then seeing its numbers, worked up the 350 with good, but lower numbers to possibly reduce those "shocks".

    With my 2F now, when I drive 65, my RPMs are 3000 and my speedo is spot on, with 4.11 gears and 31x10.50 tires. I will be going to 33x12.50 and the 5th overdrive of the NV4500, which will bring down the RPMs on the road. And as you indicate, low RPMs when off road.

    There is a WAY easier way to find parts availability than scrolling through this awesome thread.
    Just go HERE and enter your part number in the search box. If a part is discontinued, you will see it. They have always been accurate for parts availability for me... although it is doubtful that their database would be 100% up-to-date perfect.

    Don't know the part number?
    Just go HERE and find it in the drawings.
    (Numbers on Toyota drawings, except typically for bolts, nuts and washers are called "PNC" numbers. PNC numbers reference the 10 digit part number that you are looking for.. at this site the part numbers are at the far right of the page).

    windshield install

    kevinmrowland said: ?
    I ask since I've done a half dozen or so of them with that strip, and it's a pain, but as long as it's slick it slips into place.
    The tightness is a plus in my book, it is after all the expander strip and in that case tighter is better. I've always found much worse rust under the aftermarket window gaskets that do not have the slot for the expander strips as compared to the OE style expanded ones.

    He mentioned exactly that issue, but said it was because of improper installation, not because there's anything different with the aftermarket seal. If fact, if someone is going to try a home-installation, it's the only way to go. I held them side by side (sorry, no pic) and in fact the Precision gasket looked beefier. Had I not already bought the Toyota gasket, I would have gone aftermarket.

    Dirk said the step most places leave out (and it's in the FSM procedure) and always left out by the installer-comes-to-you guys because of the time it takes, is the final Urethane sealant step between the glass and gasket lip, not just the application between the gasket and window frame. It did take a bit of time for that final step and subsequent clean up, but he said it was absolutely necessary for a leak-free install. He also showed me it had not been done on the window he just removed from my rig... Thus the rust, and fu#!*ng water on the driver's floor boards I used to get. :crybaby:

    MUD member and FJ60 owner, and one-time in the auto-glass business "Tinker " mentions the same thing over and over in the various other windshield threads he's posted. In my first post, here, I link to another thread where Tinker affirms this.

    Did I mention I love my new windshield? The world is open, again :p

    What is your current cruising RPM? Shoot for getting your peak torque at that RPM as that will offer the best mileage. Not sure if the book goes into Brake Specific Fuel Consumption or not, but BSFC quantifies (fuel consumed per HP) and this always happens at peak torque. By running at, or just slightly under, peak torque you're operating at max efficiency for that engine combo.

    Have you considered the GMPP replacement aluminum Corvette heads? Those will let you run a bit more comp ratio while keeping to a small, high velocity intake port.

    At 65 MPH I am doing 3000 RPM at the moment.

    With the future overdrive, which I remember is around a .8 over factor, would put it around 2400 RPM plus going to a 33 size tire on 4.11 gears, I say 2200 to 2600 RPM target range, which matches with the above TQ numbers

    as to the Corvette Alum heads, I think you are referring to the Fast Burn: below is what I found on a personal sale (they are more expensive for sure from retail);

    Default FS-GMPP Aluminum Vortec Fast Burn Heads, Cam, Lifters, Rockers, more... BRAND NEW
    I have the following absolutely BRAND NEW GM Performance Parts from a NEW ZZ383..

    62cc Combustion Chambers

    -This head is a bolt-on 30 hp increase when used on GM's ZZ4 crate engine (according to GMPP)
    -Sells for $650 EACH new

    + Shipping

    [he lists other parts he is selling]

    at his price, they would match the same price as the Iron GM vortecs I am looking at.

    Here is a jegs listing for them at retail:

    They are a big port runner at 210cc, which more for HP and not Torque

    are you sure that intake you linked to bolts down to a 5.7 vortec cylinder head? Are you aware of the differences between the vortec heads (like are stock on a 1999-97 GM truck) vs. the older school 5.7 cylinder heads? i'm referring to the bolt pattern and number of bolts used to mate the intake manifold with the cylinder head.

    At one time the only 4 barrel intake for the 5.7 vortec head was one offered by GM / GMPP.

    make sure you understand the differences before jumping off into that. I think the 5.7 vortec heads are good for a mild engine which is what you would want in the off-road torque business but as I noted the intake selection for 4 barrel carb use was and maybe still is limited. There are some people who drill the intake manifolds...i'm not one of them.

    notice the number of bolts used to fasten the intake to the cylinder head.

    On a 383 with small Dart heads I get a little over 400 ft/lbs by the time I hit 2k rpm, it peaks at around 330hp and 450 ft/lb but runs out of air by the time you hit 5k. That is enough to grenade pinions, driveshafts, hubs etc. All with some shock loading as someone mentioned earlier.

    That is enough to easily pass trucks on the interstate with authority and pull most any pass fast enough to get arrested. Makes chugging along at idle easy as well. Welcome to the dark side!

    sorry, this is in a 40, should apply to 60 too.

    GM Performance 12366573 - GM Performance Vortec Dual Plane Intake Manifolds - Overview -

    I would have bought the above intake if I had gone with a carb for fuel on a 5.7 Vortec.. THere may be other manifolds out now (5.7 vortec + carb)...but this was one choice for a while or may be one of the few choices today. I've not looked at the choices for some time, since I jumped into fuel injection.

    I doubt the issue will be too much torque from a small block.... in fact I would not go crazy chasing that dream on a stock type truck. Remember why folks run fuel injection....for offroad the truck never runs out of fuel due to engine angle and make some good power and reasonable fuel milage. With a carb you certainly can go crazy with modifications.... but I would not...a lot better to have a quasi stock setup thats dependable and less prone to maintence issues.

    Lehi, Porter Rockwell's home town
    Edelbrock makes a very nice dual plane manifold specific to Vortec heads. I have been using one for the past ten years. It currently sports a home made (ok, red neck) TBI adapter plate and big block throttle body.

    Norsk, I think you may find more usuable torque and certainly better economy with a cam that has no more than 212 degrees at .050" The larger cams make more torque, but not really the type of power you can hook up the a 5000# trailer and be happy. They're great for hot rods, but not always for trucks. The overlap is very effective for cylinder charging at low RPM, but you pay a penalty with mileage and heavily loaded operation. The overlap is not good for use with FI, which as I recall, you plan on doing sooner or later. The unburned fuel that makes it out the pipes due to the overlap tells the FI to go leaner which is really doesn't need to do in that case. Go with a roller cam and go with some good lift, moderate duration. Just my random thoughts...

    The link I gave was for the "shiny" version, the standard version is at Edelbrock 2116 Edelbrock Performer Intake Manifolds for Chevy

    and yes it is a Vortec manifold with 4 bolts each side, and am aware of the differences, and it is a spreadbore. I found it after multiple searches.

    that gives me a limit, which I don't want to approach. Once over 500 hp, the entire bottom end would need an expensive upgrade from what I have spec'd out. Instead of a cast crank, I would need a forged one and those add another $600, plus better rods, pistons, etc.

    my range I am figuring is idle to 5500 RPM, the Sim charts indicate TQ and HP drop rapidly after 6000.

    Those are not the heads, and it looks like the heads I had in mind have been dropped. Not finding them on the GMPerfParts page. What I had found is a aluminum replacement head for some year Corvette that had a 165cc intake port. With that small intake port volume they would've worked really nicely on a low rpm 350.

    good info.

    The Edelbrock is also a Dual Plane, a Vortec and a Spreadbore. Designed for idle to 5500 RPM range.

    That link is a square bore and I am wanting to do a good rebuilt QuadraJet. Have been researching that and found a great site at Cliffs High Performance Quadrajets :: Qjet Carburetor Rebuild Kits, Parts, Quadrajet Rebuilding, Quadrajet Parts, Bushing Kits, Carb Tuning

    I bought his book via Amazon which he wrote back in 2006. He has been building engines for 40 years. Owns a 1973 Pontiac Ventura, which has 650 HP 600 Ft-lbs and runs on his own tuned Q-Jet. It is his Daily Driver AND his racing vehicle. Fairly good mileage if he stays out of the secondaries due to his tuning. I have found that the Q-Jet is a great carb, BUT must tuned for the application in order to idle, off idle and WOT work right. I have learn ALOT about carbs from this book, talking with him and actually doing my rebuild with his HP-kit. One thing the Q-Jet does well is on off-road vehicles on angles, due to the design of the float, bowl, etc.

    I want to do the Carb thing at first and play with it.

    yes I'm told the q-jet is the one to have if running carb off-road on GM-V8...I would do the same.

    Q-Jets are great carbs....espically for anything that's semi-mild build, I think they are the best for many mild street and off road applications...only when you really get into the hard-core hot rod or race stuff does a Holley really come into play. Getting hard to find local people who know how to work on those things now-days that everything is fuel injections. Q-jets are not hard to work on either.
