Hi guys, it turn out the 60k mile l98 350 engine i was going to buy was a 305 with 100k miles on it. So i got screwed on that deal. Now my dad found a 96 lt1 with 21k miles on the car today with tranny and fulling harness for $1200. He drove the car that had the engine in the car and sayed it ran great. So what i need answer is a question that has probably been on here 100 times. What do i need to do to change all the l98 components to lt1, is the driveshaft the same size? how hard is it to change all the wirring harnesses? I really dont want to mess with the harnesses because of what a pain in the *** it look like but i guess i will have to do it. If there is a how to on this please send me a link, or if you have personally done this swap please give me some info on it. Thanks alot
Bobby

 

We have a "Motor Swap" board that would probably be more usefull for you considering this is stricktly tpi.

You'll want EVERYTHING from the car, Driveshaft to radiator, i mean everything. Its a reverse cooling system, so this is why you need the radiator, you need the harness because its a completely different ECM style including both MAP and MAF sensors, you'll want every last piece you can get your hands on.

Z28Racer did the swap and his car just started running

If he's in a good mood he might have some more info for you.

 

I alreay posted in there i need all the help i can get. Thanks alot for you advise.

With the drive shaft off the 96 bolt right up to my rear end in my iroc? With the lt-1 in my iroc and tranny with the lt-1 driveshaft fit perfictly to my rear end or will i need a custom made driveshaft?
thanks again
Bobby
