why do you want to spend so much money on pistons for a van engine ?when cast pistons will go past 100.000+ miles i could see going to a hyper speed pro the 5/64 is a thick ring .078 did you say you wanted to run 043. rings in it ? you can buy a head with a bigger chamber srp are $458 speed pros are $320.if your pulling any thing heavy your never going to know the quality of the fuel is till it is in the tank. so i would keep cool on cr not a hi cr engine any thing over 9to1 would be more then i would want to do you should not need any more your building a stroker and that cam will not need any more cr to work good .did you try that piston in the PBM brand may be abit less if you must have the mahle piston. is your machine shop going to be cool with you walking in with your own new pistons ? i would think my cost is better on them pistons but the guy at your machine shop i am sure wants to make some money on parts?
