Anyone with an AMC inline engine should go to
www.amxfiles.com and join the amc-list.
I've been a member for a few years & is my best read daily.
Active membership with quick answers & parts availability & problem solving.
Another group is Strokers@yahoogroups.com >
this group take the AMC / JEEP 4.0 and install the 258 crank into the 4.0 for a 270+ HP result.
There are quite a few who install the '#630 or #7120 4.0 cyl. head from a '91 to '93 4.0 along with the EFI onto the 232 thru 258 engines for a great result. Comp ratio is higher so you have a Performance upgrade along with the EFI for a fantastic Inliner 6 > about $200.00 all said w/0 CPS.
If your running an AMC > these are the guys generating the Action.
