LT1 383 4l60e FC TII
« on: August 09, 2011, 10:12:59 PM »
It's time to share some of my build. About 7 years ago a did carbed SBC T350 conversion in a rough FC. I loved the car but sold it at about 95% complete. I told myself I would do another someday.  As luck would have it, I came accross a 88 Turbo II in good condition. The previous owner pull the engine thinking that it was bad (turbo problems). I got the car as a roller with the engine and trans along for the ride. I paid $800 for the car and sold the engine pieces and misc parts for around $500. In the end I ended up having about $300 in a solid TII.





My next step was deciding what engine/trans combo to use. My first choice was a LS with  a T56, like alot of guys are using. I love the idea of GREAT reliable power. Then I though about doing something different, like a Toyota 4.7 V8. I know it can be done, but at what cost (money and time).  In the end I ended up going with a LT1 and 4l60e for two reasons. First, parts are cheap and fairly abundant. Second, I already did a LT1 conversion in a 1997 Jeep Wrangler about 3 years ago. So I know the engine and already have alot of parts.




Now that I know which way I'm going, It's on to the build.

Engine
95 camaro block
Eagle "SIR" rods
Used 3.75 forged crank (didn't even need turned)
Probe SRS Flat top pistons
Comp 503 cam & GM performance parts springs
Stage 1 porting to OEM heads
Electric water pump
BBK throttle body




Start of my custom harness. Wish I would have bought a stand alone harness :'(



Engine and trans in, most of the wiring complete.
Cooling system mostly done (need to repair heater core).
Summit radiator with  a Taraus 3.8 fan.



Things that need to be done.
Exhaust- thinking of building my own headers
Shifter- looking for an OEM auto shifter. let me know if anyone has one for sale
Drive shaft
Clean-up wiring
Roll Bar
Reinstall interior- plan on using OEM gauges with modified speedo

Now that I have the thread started, I'll try to keep it more up to date.

Pictures are always nice.
The LT1 is a good inexpensive platorm  , I've been driving a LT1 FC for the past 2 years.
I also have a stroked motor and pushing 391RWHP and same amount of torque with some restrictive 1 1/2" shorties with a single exhaust line.
I've put 15,000KM just this summer with my car.
I love it.
Keep posting progress of your built . :cheers:
Martin !

Nice work! What are you using for your intake elbow? It looks like a silicon elbow, but how does it not collapse with the rubber bellow clamped to it?
