You are going to need the wiring harness and pcm for that LT1 - there are lots of aftermarket companies that can help you out with that. If your '88 originally came with a V8, the LT1 should bolt right in.

Default lt1

I have a 1990 ss454 pickup i just yanked an lt1 out ofto put an ls2 back in. If you need a harness i will be selling one. One thing to watch for is the camaro accessories. They put the a/c compressor on the bottom. We ended up notching the frame and welding a piece back in. The corvette runs accessories that you would not need to do this to, that would be your best bet.

Just currious on why was a LT1 in a 454ss? I am pretty sure that is not the stock engine.

I added the lt1. Was'nt fond of the 10mpg and 15second quarter mile times of the 454.

I am interested in this as well.

Any differences in a 93 z71 5.7 and a 96 z71 5.7 vortec other than intake and heads?

I know the LT1 shares with the Gen I sbc as far as bolting in. But aside from wiring harness is the fuel system the same?
