My little 3.4L is soon to be an LT1. Please read I have a question.
 

Hey all. So I've had my 3.4L for 3 years, this was my 1st car, and I've done everything to it myself. I tore the motor down and rebuilt it 2 years ago. Each year putting on more additions. I Love my little 3.4L But i feel its time to move onto the bigger motor. I got a great deal on an LT1 and Harness. I'm 95% sure i can do this swap, and if i needed any help I have at least 3 people who are willing to stop by and help me. This is what i am getting and I just want to make sure my F body can make the change from a V6 to a V8.

1 Lt1 Motor
1 ECU
1 Wire Harness
1 A One Peice Drive shaft
1 Intake w/ MAF
1 Z28 rear end ( Posi rear )
1 150mph Speedo

I already have the Chasis, 4L60e Trans, with a transgo shift kit installed, but It feels like I am missing something. I will buy an aftermarket exhaust from the block back. Anyone know of something else I may need to complete this project?

get ready to spend at least a grand more than your planning.lol. there is ALWAYS more. sorry but its the way things roll. example i always use is my 300 dollars headers that turned into a 1000+ dollar project after i got everything i needed.

i've done alot of research on this same swap. I think though if i read right you wouldn't need the 150 speedo. you only need the engin compartment wiring for the V8 not the dash.

you do need the speedo. your v6 one will be incorrect.

yeah i read the sight you posted on the other post. I don't know what the people at ummm...camaroZ28.com because that is what they were tryin to say. but hey i won't argue

I do need a 150 speedo, i could make it with a pen an paper it wont effect the engine, just effect the speed i THINK i am going and the tach will be off. I don't need it... But want the job done correctly and I want to know when i'm going 10mph... or 40 mph. Know what i mean lol.

Oh an about spending 1k over what I plan. Haha, I know about that unwritten rule. I'm getting the motor for a great price from a buddy. He has 2 of them I am considering buying both. I will put an lt1 on my bicycle or something...
