oldscout401 wroteCheck out Superior Automotive Engineering in Anaheim.-(714) 503-1880. They are expensive, but meticulous. Or for a stock rebuild I,ve used Orange Engine, also in Anaheim.-(714) 634-4030. This guy has owned a few AMC jeeps and has a clue about AMCs. If you want to bulid a bigger motor, I might be willing to let go of a 73 401 for $700.00. Its never been bored and still runs good.
I've used Superior before and they are great but you're right...very expensive and Orange Engine is just around the corner from me. I didn't know he was up on Jeeps though..
$700 huh?...where ya located?
