hey 35, i just pulled a 4 cyl. out of my 1997 s10 and installed a 1993 LT1 - 700r4 in it. i used the stock wiring harness but the after market one might suite you better because they have clean them up a lot. you need to look at the ac comp. on the right side bottom unless you are planning on buying all new brackets, the LT1 will need the high pressure fuel pump with return line, there is 2 sets of boss on the block for the motor mounts, one for late models and one for early models i used the stock computer so i had to have a new chip made before i could crank the motor because the burglar alarm was built in to it. on the 94 up they don't have a chip so i guess they would have to reprogram the computer for the dif. ign. switch. ive got another 93 tran am setting in the drive way with a LT1 in it just waiting to go into something. i like the computer, EFI systems. if had a new 35 project id put every elec. gadget on it i could find. i guess you know that the dist. is behind the water pump, and is cam driven with a small shaft, and the water pump is shaft driven with the cam also. you also have to run a elec. fan on the LT1 because the water pump is not made so you can put a fan on it. you didn't say how much of this you could do yourself so i dot know what you really need to know. if this is not what you was looking for let me know.
