anyone got the full specs on the 4.0 I6 (valve size, bore size, bore stroke, exhaust manifold diameters etc..) I've got dyno 2000 software and i'm trying to calculate performance addons for the 4.0... is there a major diff between the older 4.0's and the newest ones from daimler/chrysler? I've got a '93 and I'd like to know.
Awwwwwwwwwwww... So he wants to go OFF-ROAD does he????
