OK on the wiring what am I going to need to modify the engine harnnes? I did not get the body harness he didn't have it. It has 1' 5/8 headders and 3' y pipe and a LT4 Hot cam needs valve springs changed but I'm going to tear it down and do some head work. turn crank all the good stuff

 

The headers won't work if they are for a 4th gen car. As for wiring, as long as you got the engine harness, it's really all you need. I picked up an extra underhood harness w/ fusebox, stripped out all I didn't need like the ABS, that way I had a stock plug to put into the PCM for the fans, A/C and cruise control (for when I hook the 4th gen cruise up). Injector power switched, PCM constant, PCM switched, ignition power switched, oil pressure, temp, tach, speedo, and the purple start wire that I ran to the starter should get that motor running good.

 

The headders are for a 3rd gen I got that one you showed me on HPT where did you get the under hood harness? Tenn auto?

 

Yup, pulled one out of a '94 Z28

 

Looks like I'll give them a call.

 

what about vaccum lines any where I can get digrams of these?

 

I just pulled an LT1 from a 95 Camaro to put in my 84 TA recently, and there wasn't much in the way of vacuum lines. There is the large vacuum hose that connects to the brake booster and one other small line off the manifold. The small line has a y-connector/ check valve that goes to the vacuum ball and to the HVAC diverter controls. I haven't figured out how the charcoal/evap canister is operated yet on the 4th gens, but it doesnt require a vacuum line like I believe the 3rd gen ones do.

 

There is a vacuum diagram sticker that is placed on the radiator cover on 4th gens. I'll try to get a pic of that and post it later today or tomorrow.

 

Also is there any difference between the tranny's in the buick's and camaros. Besieds the T.C.? I can get one from a buick roadmaster alot cheaper than one from a camaro/bird?

 

or mabey a t-56 anybody know about the transmission's?

 

Need the rear housing from a f-body 4l60e. Might have to have the same year of 4l60e as the LT1 you are putting in.

T56 - 94 to 97 are prettty much the same on f-bodies.

 

Thats all that you did? I'm finally to the point of wiring mine right now. The fuel pump relay stuff is giving me trouble because there is more than one green/white wire. Grrr. Should I just wire it to come on with the key??? I was worried that the PCM wont let the car start if the feedback wire wasn't connected.
