Intro/Difference between AMC 304 and 360
 

Greetings. I've been browsing the group but this is my first post.
I've been a CJ owner since around 1990; I'm on my second one right now.
Had a break in ownership while I was stationed overseas.

Here's my question. I recently did a swap from a 258 to a 304 in the
Jeep. I rebuilt the 304 mostly on my own and as this was my first
attempt, it is now broken. (I'm overseas again and my wife said the
guy at the shop said, it was a piston skirt).

Anyway, if I need to rebuild this thing (again) I thought I might as
well "upgrade" to a 360. Is this possible? What are the differences
and what would I have to change? Just the crank, rods and heads?

I've googled the heck out of this and can;t find anything.

Thanks in advance for any help and have a cold one on me while you
think about it.

The difference is 56.

Here is another angle for you to think about. How about a 4.2 crank in a
4.0 block using the factory fuel injection? Good emssions, decent mileage
and the reliabililty of modern fuel injection. Join the Strokers Group and
spend some time poking around. This is the way that I am going when the time
comes. 275 ponies and over 300 lbs/feet of torque, those are V-8 numbers,
without the addded weight of a V-8 up front. I have included a couple of
more very good sites with lots of great information. Dino Savva has done a
tremendous job with the second website.

The 360", 390", and 401"s will bolt straight in, no surprises such
as externally balanced flywheels found with other engine manufactures:
The only way you may tell them apart is by their cast cubic inch number
found under the driver's side engine mount:
