10666 is for a 331 or 347, so no they wont work

I'm new to the whole piston thing, can you reccomend a set that will work and bump up compression?

93StreetFox

No piston experts out there?

the cc of the head chamber will limit your compression somewhat.........are you having the block bored .030 over???

also why go to all the trouble of boring/rebuilding/buying pistons,rings,bearings,gaskets and more for nothing less than a 347 with a good h/c/i ....just throw some juice to it

Well i can't afford a full stroker kit, dont feel like messin with the juice. I just want a solid 5.0. Mind you i already have two cars that are fast enough. But would having it bored .30 over be somethin that i need to do in order to get some compression. My buddy said some flat tops that'll get me to 10:1 would be good enough. But i dont know which pistons to get that will do that.
