I have a guy thats got a dissasembled 429 with a master rebuild kit. It has pistons, rings, bearings, cam and lifters, gaskets. What I was curious about was with the block. Its used so wouldnt the cylenders need bored out? In which case, that would also require larger pistons right? I dont think the master rebuild kit has a crankshaft(I dont think), so if the crank needs turned, its going to need new bearings of a larger size. And cylender heads are a whole different rebuild altogether right? Just looking for some kinda info.
