Or if you are running boost and want a small shot, the 2618 is the better choice. Don't get me wrong the 4032 is a great piece, we are currently doing a build that we are going to 14psi on a KB(not recommended). The thing is on this build we are upgrading inner coolers, spraying water/meth, etc to keep the engine from knock. I like the 4032 for the long haul, tighter clearance, higher silicon material etc etc.. The 2618 means a little more noise and clearance. But after making the first run it seems the questions always migrate to the upper end of the scale. If I were doing an NA or a good reliable 10 psi street car I would go with the 4032. Remember I built the first run to replace a cast piston and work with the stock rod and balance, not a all out forged 6.1 build.

Only if we make this run from 2618 would I run 15psi

I will start a new batch today if I can get a couple people to commit and send deposit. Show me the interest and I will place new order ASAP.
