4.0L HO Jeep Engine Build

OK, been doing a little more research via the link that Mopekid kindly provided and realized that the factory installed this cam 8 degrees retarded! I know that Ford did this to decrease emmisions in the mid 70's which really turned a lot of potententialy good engines into dogs.

This is really a an HO engine from the factory and was wondering what would happen if I advanced the cam from it's present setting to straight up or only 4 degrees retarded? Decisions, decisions, decisions.... I can get an offset bushing kit for about 30 bucks but I sure as hell don't want to tear this thing back down if it runs like crap. Also.... since the distributor is non-adjustable, by advancing the cam, I'd also be advancing the timing by a TWICE as much in crank degrees with no way to dial it back.. Hmmmmm.

I better leave it the hell alone, lol. Dang computer cars....
