Timing cover and reluctor wheel fit. Use the Vortec balancer.
Which cam are you going to use? Vortec use roller cam
Well here is my dilema. Right now, I have a complete 383 EFI engine sitting on an engine stand in my garage collecting dust. It was in my 91 Z28. It is a 1pc rear roller engine. It has a Holley Stealth Ram intake, AFR 190 heads (72CC), Comp cams 224/230 .502/.510 112. Rotating assembly is a forged Eagle kit with JE flat top pistons. This engine was insane in my camaro.
I also have a complete speed density TPI intake setup sitting in the garage collecting dust.
Option 1: buy a stock L31-R GM crate engine and just toss it in my truck and be done with it.
Option 2: buy a stock L31-1 GM crate engine and put a mild cam in it and toss it in the truck
Option 3: buy a stock L31-R GM crate engine and put a mild cam and the TPI intake on it and toss it in the truck. (wiring mods will have to be done)
Option 4: buy a new 350ci short block and use my AFR heads and TPI intake and toss it in the truck.
Option 5: use the 383 short block I have and buy new Vortec heads for it and use the stock L31 intake and spider setup. (Possible cam change)
Option 6: buy a new HT383 Vortec crate engine and toss it in the truck using the stock parts from my L31 engine. (most expensive option)
I am also reunning the 0411 ECU in the truck. Truck has an upgraded exhaust but still uses stock manifolds.
Will the TPI system on top of a new L31 crate engine give me more torque and hp over the stock L31 intake and spider injection?
