GOAL: BUILD AN EXPEDITION CLASS FJ-60
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)

History
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 CruiserOutfitters.com)
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
Desmogged
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.
*********************************************************************************

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:
350
TQ 493 @ 2500 sea level (403 @ 2500 5500ft)
HP 383 @ 5000 sea level (313 @ 5000 5500ft)
383
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.

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.

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:
350
TQ 493 @ 2500 sea level (403 @ 2500 5500ft)
HP 383 @ 5000 sea level (313 @ 5000 5500ft)
383
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.
