I don't think it will really roar until I can get it tuned... I'll still need to redo the exhaust. Not sure If I want to do a true dual 2.5" or dual 2.5" to single 3" cat/ muffler.

heheheh, Mace beat me to it... thanks for the pics. Maybe a shot straight on would help? What kind of springs are those?

I've got to redo my exhaust now too. After the springs settled my front driveline is getting to the crossover from the passenger to the driver side. I need to tuck mine higher into the oil pan. It'll only the the billionth time I've redone it. I've gotta pass deq in a couple months and I have to put the cat back on after it mysteriously fell off one day.

Here's a few pics. it was difficult to get any better pics

few more

the springs are fj62 springs with a few leaves added. This is the 4th set of springs on her since she was sprung over 7 years ago. It eats springs. These ones should hold up well.


Here's a pic of the stroker half installed for posterity. I REALLY need to clean up the engine bay. There are wires and hoses going EVERYWHERE!

[brokenparts]

bingo... those are exactly the pics I was lookin for. gracias. Dude if you think your bay looks bad, you should see mine. I need to do a motor swap so I'll be forced to clean it up.

[sixty]

Update... The engine is put together and fired over as soon I got the timing close. Its running very rich with the 75lb injectors, so I'll probably swap out to the stock 55lb until I can start tuning it. It sounds like a beast!

Couple of pics (its a shame to hide all the bling under a mass of wire loom and hoses):

[Mace]

I thought my wiring was bad


Looks awesome amigo!!

[brokenparts]

Man... that would frustrate the heck outta me tracking down all the wires/lines/tubes. Glad to see with enough patience it can be done. Nice work. Now post some vid of the motor running.

[sixty]

Its alot easier than it looks.... If I had more patients and wanted to spend a bunch more $$ on it, I'd redo all of the wiring and hoses. With all of the accessories I have (OB York, A/c, ARB, Auto trans cooler, hot water shower, remote starter solenoid, etc.) it would be very dificult to make it look simple & uncluttered! (that & I'm too lazt to spend 2 or 3 solid day redoing everything)

It was far less dificult than putting a 2f back into a 60 with all of the smog crap! I did all of this by memory, whereas I don't think many guys could do that with the 2F smog lines.


Now I need to get my exhaust figured out. its probably going to be 2.5" from the headers to a 3" cat & flowmaster. I'm tempted to run dual 2.5's but that would take up alot of space.

[brokenparts]

I tried doing duals... just not enough room in there.

[sixty]

I might just turn the block huggers over & go straight pipes thru the hood. My wife thinks it sounds pretty good with straight headers

How much Rich it's rich .. ? just to know what expect with 75lb injectors ..

[sixty]

Its probably in the 10:1 range if I had to guess. there is no black smoke but the hydrocarbons in the exhuast make it hard to breathe in my garage . The reason it runs so rich is that the compurer thinks it has 55lb injectors & is fueling accordingly. At 19psi the 75lb injectors are more like 95lb. As soon as I start tuning I can lean it out pretty easily. It will have a much more stable idle with the smaller injectors at higher psi since it will atomize better. I may stick with the stock injectors at 35psi to make them 95lbs +/-

Tuning should be fun!

Thanks Sixty .. damn pretty much .. I was expecting 11.5 or so .. but 10:1

[sixty]

10.1:1 is just a guess... There is no fuel dripping from the headers but the smell is real strong. I haven't looked at any plugs yet.

[brokenparts]

alright back from the dead... Let's here your spec's on the TBI motor...

[brokenparts]

What do you think of these heads and rockers for part of a TBI build... Gunmetalcruz on pirate has a set assemebled that I'm considering buying from him for my anemic TBI.

Those are a great set of heads, you just need to make sure you pair them with a set of pistons (to keep your compression in check, around 9.5:1) so you can run 87 octane. Pair that with a large cam with an LSA of around 112-114 (a roller cam would be very nice if you stay with your TBI block)

If you don't need an EGR for smog, you can get a Weiand single plane manifold and not lose your low end, since your using TBI.

Those crane rollers are very nice but you'll be into them close to $600. You would be better off buying the summit rollers for around $200 Summit SUM-G6910B - Summit Aluminum Roller Rocker Arms - summitracing.com with not much loss in quality.

In my opinion, you would be much better off buying an engine that someone already built & needs the money. I paid $1500 for my stroker that I could not have built for less than $3500. Keep your eyes on craigslist and pirate, there are some great deals out there if you are patient.

[brokenparts]

ok, so I found this one... the guy selling this is on a couple local boards and seems somewhat reputable. w

What cha think? I just emailed him for some more specific info.

Thanks for the resurection!

Here are the specs:

4-bolt main, high nickle block .040 over, .010 on the mains
Scat 9000 crank with scat 6" rods, int.balanced
KB Hypereutectic pistons @ 9.6:1 compression
EQ torker 76cc heads (supposed to flow slightly better than vortecs)
Comp Cams XE 4x4 K12-239 cam (only 111LSA)
Summit 1.5 roller rockers
Edelbrock performer intake with EGR (I need to smog)
All ARP bolts and studs
Ebay ceramic block huggers
50mm (700cfm) bored throttle body with a vacuum referenced fuel pressure regualtor set to 38psi using the stock 61# injectors.
EBL modified ECM from Dynamicefi.com
Airtex External 90psi fuel pump, only $30 from EBAY!
Moates.net wideband meter with the Innovative LC-1 controller

I built the exhaust last weekend from mandrel bends bought off of EBAY. It is 2.5" to 3" into a 3" magnaflow cat and HUGE magnaflow 3" stainless muffler. I wanted it to be quiet since I seem to do alot of road hunting now that I'm over the hill it is a quiet exhaust. I could have had an exhaust system built for about what I paid for just the bends. this would have saved me about 8 hours of work, but the mandrel bends flow much better and the routing is perfect.

When I first fired the engine, I had a loud knock coming from the bottom end. it sounded and felt like the crank was hitting the pan (common in strokers). I pulled the pan & saw nothing so I racked my brain, cut open the oil filter looking for bearing material, checked all of the block clearances & finally decided it must be coming from somewhere else and started reassemble it. when I was cleaning the oil pan there was a little lip above the windage tray that had amall marks on that coresponded with the # 4 rod & sure enough that was the problem! Bent the tab down, got it all back together & the knock was gone! I'm glad I didn't start pulling the bearing caps.

I also installed the EBL board into my ECM & it is an awesome computer. The software is very user friendly & it will actually learn while you drive. I still need to install the wideband to make the learning much more rapid and accurate. It is similar in operation to the megasquirt, but seems to be alittle better suited for performance and is tailored to running the GM systems. It can be configured to run cooling fans, nitrous & blowers. Unfortunately it does not yet support a Maf sensor, only speed density.

I still need to install my VSS. I am going to use the rostra magnetic sensor for a cruise control. The guys over on the binders bulletin have had success using them with TBI. you can get them at summit here: Rostra Precision Controls 250-4165 - Rostra Vehicle Speed Sensors - summitracing.com

I also need to wire in an IAT sensor (Intake air temepature) so the EBL can better compensate for changing temps.

I'll update this thread sometime this week with pics of the exhaust.

I saw that over on Pirate, I posted up asking the specs on pirate but I don't think he ever responded. I didn't realize it was local to you.

If it truly has low miles, that is a killer deal. Find out what parts it has and verify the condition by pulling the pan. You should still be able to see the cross hatching on the cylinder walls. He does not mention what the compression is, so you may need to run premium. If he still has it installed it would be a good idea to drive it or atleast hear it run.

A large TBI with an EBL would work great on that engine.

Also, make sure that the heads ae newer and have the 3 mounting bolt holes on the front. You can then use your serpentine setup just like stock.

[brokenparts]

thanks for the good info... I might have to look him up and wander over there for a looky lue. Not sure that my toy junk/th350 is up to take that much abuse though.
