Well I have a 400 block bored .030 over (4.155) and I have a 3 inch forged steel crank thats is going in the 400 block to build a 325. What my question is what rod legnth and compression height pistons will work?

I know (1/2 stroke + rod length + desired piston to deck) - deck height= Piston compression height. But what other length rods/pistons do they sell? and who sells them?

I think .025 is the right piston to deck clearance right?

And is it better to have longer rods and shorter compression height pistons or the other way around?
