225 Rebuild from scratch

I am not the guy to speak to those rods.... Does the 9-12 psi boost get you to a goal that 8 psi of boost does not? 8 psi will be a nice improvement and will stay in the realm of solid daily driver. Somewhere in the 9-10+ range, the torque starts to really step up.

If 'twer me, I would go with stock parts (rods/crank) for now, and get it running well with static compression ratio of around 8:1, and then go limited boost later if I wanted. Maybe polish the rod beams and shot peen them.

And I am not up to speed on the /6 pistons..... hypers for the /6 aren't popping off of the internet like for V8's, except for the KB 2.2 ones that you would use with the longer 170 rods. See here:
Stroking the Slant 6

So that leaves the Wiseco forged pistons but now we are getting into budget questions.
