And finally a 1981 jeep cj7 258 hardtop
Well I finally got off my but and went and got the AMC 258 i6 / 4.2l at my friends in crestview. I've got it tore down to the head and block. What would yall do with it? My present AMC 258 i6 / 4.2l is in perfect condition. I'm in no hurry.
 
Keep block / head for spare or sell them, and keep crankshaft & rods for stroker project. :D That is what I did with my spare 84 engine anyways.
 
I have a spare also it's been sitting in the corner of my garage sometime now. I've been stealing parts off of it for my Jeep and others. I just like having a spare around because you never know.
 
I have a spare.. its bored .060 over,has a thin head gasket, 4.0 head, custom cam and arp studs.. runs about 10.5:1 compression. Im afraid to put it in my jeep

Shucks, I'd a thought that you would have fired it over by now...It definitely was a beast to run...but premium plus extra lead does get pricey!
 
I've got a spare on a stand that I'm probably going to rebuild with the 4.0 head swap.
