[offrd3]

ok i was wondering if andyone has delt with this i was looking for the sealed power pistons on the summit racing website and they had two different ones the z677cp and the 677cp. I don't see any difference in specs but there is a $9 difference in price. what do u guys think, thanks

I think they are the same piston: cast(not hyperteutic, as the h802s and h825s are) with the coated skirt(thats what the c stands for) Get the Zs since they're cheaper.
