Re: 4 to 6cyl. engine swap??

you'll need different driveshafts, a new bellhousing, and new motor mounts.everything else will work fine. you might want to think about a better radiator depending on what you have.

Re: 4 to 6cyl. engine swap??

Who's 6 cyl?? Jeep or another one?? The one I ended up using was a 229 Chevy V6 (their 3.8 litre) out of a mid-eighties Camaro with a carb. It bolted right upto the bell housing. But, I did have to get a different flywheel (standard 153 toothed GM) and clutch. Good luck on this one. If you're input shaft is the 1" diameter and is 14 splined, you'll have to dig around to find one that is as close to 10 5/8" (upto about 11") as possible. If yours uses the 1 1/8" diameter and is 10 splined, go get a clutch for a GM 305/307. Mine had the later setup and I got mine for a 68 Monte Carlo with a 307.

I also had to get the typical weld motor mounts for a Chevy V8 to make it fit. I also had to modify them a bit to work for me. I had to drill another hole in the arm to make it fit the bottom motor mount. I drilled four holes in each to align it with the stock motor mount location of the 151. I also replaced the cheap washer keeping the bolt from ripping through the bottom of the mount. I used a large shock washer for this.

I had someone else do the wiring (simple job though). Just thought I would give you another option to the Jeep 6.....
