I have an 88 Wrangler with the 4.2L in it. My dad is getting ready to scrap an 86 Fleetwood and offered the engine out of it to me. I've tried some reasearch but I haven't found too much on swaping the 6 for an 8. Its a Buick 305. Will it fit, and how much work would it take. Any help would be great.

They put LS1 corvette engines in jeeps a while back. I imagine a v8 would still fit but getting everything hooked up again might not be possible. It might be more trouble than it is worth if that is your only transportation. Good luck. Post back here if you get it to work.

Try this site they might be able to help you out. I think they might have the parts you need.

I hope that helps some.

if you want to drop the 305 in to the jeep u will be able to fit it but u will need a welder and alot of tools to fabricate motor mounts and u will need a match tranny and t-case and u will need to get shorter drive shafts and this can get expensive trust me i have thought about that swap mnyself i have a lil AMC 150 I4 in my wrangler i m swaping to an AMC 258 I6 thats gonna have alot of money dropped into it and i have a complete jeep with motor mounts driveshafts and wiring harness. If you want to kno exactly what u have to do email, or IM me or post another reply ill help u ive been workin on cars for 8 years now and i ahve much experience so any questions find me via IM email or the board.
