What V6 to what V8. If its a LSx you'll definitely need a K memember but not sure on LTxs

i changed a 3.4 L for 5.7 L lt1 into a 95 camaro from a 95 firebird rage top RIP :( 07/22/08. But anyway's i used the computer land harness allso had to fab the driver side motor mount an i used a three speed trany 350 turbo with a shortend drive shaft.Ran great at first but now it has a splutter to it and i think it's the fuel pump or the mas IDK :werd:

For f-bodys an ltx get the computer w/harness and rear gear changed I'm putting an lt1 in my v6 firebird everything bolts right up or if you want more get a real grandnational motor/trans and w.harness you might need a computer too if you do that you would have one of the fastest f-bodys around

I believe you'd also have to change around the DLC wiring.

Did you have to change the fuel pump for it to start?
