I have a 66 cruiser with the 283 auto, 3:31twintraction rear end, power steering, brakes etc. Has anyone livened up a 283 ? If so how? or recommendations..... I do not want to take away from the history or originality of the car by putting in a different engine. Also how wide of a rim could I run in the rear? How big/ wide of rear tire could I run without rubbing on the fenders? 50/15 to big? I'm in need of a good set of fender fillers as well if anyone may have a set.
