lt1 to ls3 wiring harness
So I have a 1997 firebird formula with an lt1 in it and I'm doing an lt1 to ls3 engine swap. My question is on the wiring harness, will a harness and computer from a 98 ls1 trans am work for an ls3?

Anything is possible, but you are going to have a tough time with the cam and crank sensors. The Cam is 1x on LS1 and 4x on LS3. The Crank is 24 teeth on LS1 and 58 teeth on LS3.
I know that they make a conversion box for the cranks, and I think people are using the early LS2 cam gears that have a 1x cam sensor on the front. You would probably need to use that cam gear and sensor along with a conversion box for the crank. Other than that it should be pretty possible.
Many people have done LS3 swaps on 4th gens.
