304 swap or Stroker kit

Sorry if this is a dead horse, I did a search on here and didn't find much. I can get a AMC 304 really cheap would that be better than doing a stroker kit? Also has anyone done the 304 swap?

Check your emission laws. Odds are that the 304 won't be legal.

x2. Plus I don't think a 304 would be a good choice over the 4.0L. A 360 or 401 is the same size as a 304 and would be a better choice.

You won't find any company offering an engine/transmission mount for a TJ/AMC swap.
How do I know? I put a 401 in my LJ

If your state has any type of emissions inspection program, I doubt it will pass.

A 304 sounds a lot better than a 4.0, but in reality the 4.0 is much more durable and is already fuel injected.

Cheap isn't always the best way to go. For me, I already had the entire running gear from my CJ (engine, trans, tcase, and axles). and it still cost me mucho dinero. One thing always leads to another......

If that doesn't scare you, start collecting parts and dollar bills. The AMC engines will bolt to the Jeep stuff, but newer jeep stuff won't hold up to too much abuse.

Good luck, Ricky

Stroker, if you have to have it in the first place. Better to spend your money on gears, suspension and ground clearance, though...

If it's worth doing, then it's worth overdoing.

Stroker. I have a 304 and a 4.0 equipped Jeeps in my driveway and the 4.0 would run circles around the 304.

Ohio does not have smog laws.

I can't imagine a 4.0 I6 ever running better than a 304.

Every 304 I have ever drove or owned has run much better than all the 4.0 I6 motors I have owned.

The big downside with the 304 is the carb.

It depends on what county in Ohio you live in. Medina county (where I live) has a required e-check using your OBD II port every 2 years, therefore I could not do this swap. Cuyahoga county (Friend in Strongsville) has no e-check, so you could (probably) legally do the swap. That's definitely something to check out with your county before you pull the trigger on the 304.

As for the "V8 vs. 4.0" debate, I can't say, having never driven a 304, but I will say my little brother's 305 camaro isn't that impressive to me as far as V8s go. I know of several V6 cars that would handily outperform it. But then again, it does sound great, being a V8 and all. At the end of the day, I'd say spend the money elsewhere, like lockers, if you already have it and wheel it.

I never knew that about the Ohio localities in regards to smog laws.

It makes perfect sense though since Ohio has so many other laws that are specific to the locality. I should have excersied more care when I made that previous incorrect comment.

Thanks for correcting me so politely and for pointing this out.

I'm also thinking more about the 304 V8 and those I have experience with were not stock motors.

Maybe I should check out of this thread.

My last CJ5 had a 304 in it. It sounded great and was trouble free but was a dog of a V8. I would definitely recommend against it. Its going to take a lot of $$$ to make that work. You could build a CJ around the 304 for around the same cost of swapping it into your TJ. If there's nothing wrong with your 4.0, spend the money elsewhere. Jeeps arent hotrods.
