they're both speed pro pistons the only difference really is the dish volume..... either way i'm not very fond of Hypereutectic pistons... they're known to fragment from detonation.... what motor and setup are you using that you need a 10cc dish to get down to 9:1 comp??

I'm running 64cc vortec heads. speedpro says with 64 cc heads, their flattops with 4 valve reliefs with 5cc piston head volume give you 9.34:1. I don't plan to do too much but I'd rather not have noise at startup.
