pistons!! help!!
 
i have my head done now im working on the block i bought eagle H-beam rods and now i need pistons je sells a forged pistion that is 9 : 1 compression but i would like to run 20lbs of boost in to this block my plan was to run 8.4 : 1 but can't find a way to get it does anyone run these pistions at 20psi? is it safe? or is there other pistions out there that can get me 8.4 : 1?

those JE pistons will be fine for 20psi. look into these.

these are going to be the most affordable pistons out there right now and they should be strong enough that the crank will break before they do. that would be in the 35psi-40psi + range

they are what i am running in my 450+whp build
