Not even close.  It's a completely different engine.  The AMC 360 has combustion
chambers large enough to take a bath in.  They are huge fuel burners compared to
anything short of an open fuel line.

I know there are a few Jeep owners on this list.  Anybody have AMC cylinder head
swapping info?  Are any 304/360/401 parts interchangable?  Any pre smog heads
that have smaller chambers/better ports?  This would be a great start for these
engines.
