Rebuilt engine 318 Question

Personaly, after I take the engine out, disassemble it and take the block and crank to the machinest for a check and possible overbore, I'd go to summit racing for there kit and customize it if need be for only the price difference of the part change. It includes everything except the exact oversize of the pistons and crank bearings, in which you'll know the sizes after you get the parts inspected and worked on from the machinest.

I would add new con rods since there cheaper new than reworking your old ones and have it all balanced. Install it all myself. I followed the book, how to rebuild your small block mopar with excellent results everytime!
