    Straight eight 263 pistons

    I am building a 263 straight 8 for a street rod project. I want to build my own intake manifold & put a turbocharger on it. Not looking for a lot of boost just for something different. I am boring it out with new pistons. A few local guys tell me any new aftermarket pistons won't take it. Does anybody make any forged pistons for this applications? This has pretty low compression so it should make a good candidate for a turbo. Any help would be greatly appreciated!

    I had a set made by ARIAS. High compression, 9.5:1 CNC'd dome. NOT Cheap. Had to send them molds of combustion chambers,both INT/EXH & EXH/INT. They have shorter skirts, modern narrow three rings and much lighter than stock. Beautiful pistons, minimal slap when cold, my motor runs great. Probably good for an extra 40 HP alone. Did I say they weren't cheap?
