Blown 383 Stroker Motor

I am having a hard time finding and deciding what type of piston to go with.Some are telling me to go with a keith black hypereutectic over a forged.Does anyone have any sugestions of what would be the best way to go?I'm planing to run 8 to 9lbs boost and mostly street drive.I would rather over build than puke everything out on the highway.

i`d use the forged blower pistons from sealed power, formerly known as TRW L2441F or something close to it, I wouldn`t trust anything other than a forged piston in a blown application. but that`s just me.

Forged without a doubt. They will stand up better. The speed pros are good for a budget engine, but srp, je, or wiesco will hold up better and are lighter. We all know what lighter reciprocating parts will do for an engine. Kindof like everything get what you pay for.

i think i know your deliema, is it that blower pistons don't come with 383 pin height? thats what i found when i started on my motor it ended up being a decision, stroker or blower, i had to go blower as i already had the induction. after getting most of the parts together i did find out that everything summit or jegs has is not in the book. i would call them and see if they have blower pistons with the correct pin height. if you do end up going non stroked i would suggest getting a 3.5 stroke crank instead of 3.48 if you have the choice i went 3.48 and ended up a little deeper in the bore than i had hoped to. those extra 20 thousants would have put me right where i needed to be. forged is the only way to go for the whole bottom end imho. i have seen a crank hub for external balance so the pistons must be available somewhere.
