Since we are all on the topic of swaps, here is my plan. Take out the 304 that is in my 77 CJ5, rebuild and "enhance" its performance in the process. Then stick it in place of my beloved 258. Does anybody have any tips for building that 304? I did see that a company(forgot the name) is now making a supercharger for the AMC V8's.... oh yeah!
304 swap into my CJ7

Hey Loki, how's this swap coming?
I think some of the cam companies put together a performance package for the 304. I think it was Crane or Comp.

Keep in mind the strength of the rest of your drive train. You might get to the point where you will be pushing the tranny a bit on the torque side.
-
I got a T150 three speed that should hold up to the 304. The 304's came with T150s from the factory.
-
They also came with the T-176 which is classified as a medium duty truck tranny. Also the T-18 will bolt up which is considered a heavy duty truck tranny. The T-176 will probably be ok as long as it was rebuilt then you can go with the Dana 300 T-case.

Yeah, actually I still have the T150 that I took out of 5. I'll keep it and possibly have that rebuilt. It had chunky milkshake for lube when I drained it. The T150 worked fine behind 150 hp but we'll see how it does with almost double that.
-
If I were you I would steer clear of the t-150 and any v8. If you use the jeep hard at all snap crackle pop! Trust me! The t-176 and t-18 are both good choices I have had all three. I have a t-18 in my jeep and keep a t-176 laying around. Just my .02 I have a t-150 I'll give you as a spare you'll need it!

cant get any stronger than the NP435.
