this motor is all original it came from the factory with 2 barrel carb and a c4, this is not a 302 boss, when we pulled the engine it had 93000 miles we bored her out 10 over new cast pistons had the rods reconditioned, had the block line bored for the new crank mains and rod bearings, new cam just a tad above stock new lifters new cam bearings new valve seats and valve grind, new freeze plugs, the original carb was sent out and rebuilt which is a autolite 2 barrel:biggrin:Mac
