well, i used to have a 76 cj7 that would do wheelies on dry pavement. it had a mildly built 304. i figure it was putting out just over 300hp. i put some 4.56 gears in it. when i floored it at a green light, the front end would come off the ground a good couple feet. it also broke alot of axle shafts and u-joints doing it. it would rather lift up the front than do a burn out.
on a side note, i also had a 78 cj5 with a very built 401 with 4.10's in it and lockers. it would smoke all for tires on dry pavement. i only did it a couple times since 33's ain't cheap.
i agree on the gearing though. there's a guy here that can lift the front (not nearly as high) in his wrangler sierra with a 4 banger. but he has trouble going over 55 mph with it.
