Chrysler went even farther by deisgning the 2000 up equal length intake. yeah, that is the worst thing about the iron intake, 1 and 6 run lean, 3, 4 rich. It's quite noticable when finely tuned. The only other thing that changed much was combustion chamber shape, but not all THAT much. And camming is hardly changed in all those years. I don't know about amc six cams past the carb days though. Lots of other incremental changes, oiling, cooling, etc but intake was the biggest, and lucky for us, you can bolt the new stuff onto the old motors. Being lazy, I'll use my stock 70 232, but put the 81-up manifolds on it, with TBI. No custom pushrods, funny oiling issues, etc. I've got one all hacked for the external oiling, too, but I could do the standard fix that's on Matt's site. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
