What it the max overbore on a 96TC? I'm thinking about going to a 103 or 107. I know 103 is no problem, but how big can you open up the stock cylinders? I want to use my cylinders to keep it matched and the cost down. Looking to go with flat tops for a little more compression. Cast or forged? I will have the heads ported also while they are off. I have V/H pipes, A/C, EJK and Andrews 37H cams already.
