who's got 4.500 pistons?

i'm ready to order my pistons for my new build. who's got really nice pistons that you would recommend for a 4.150 stroke with 7.100 chevy rods. this will be for drag racing and maybe a trip around the block. i'm sure that i'll be ordering flat tops to acheive 12.1 comp. thanks for any sugestions

I've got 4.5 bore pistons from J&E and Diamond with 7.100 rods one is a 4.5 stroke and the other a 4.25 stroke. Depends what you're trying to do. consult with the manufacturer.

With 4.150" stroke and 4.500" bore, I take it you will be using heads with around 84cc chambers to get that CR. Are you trying to make a pump gas motor? IMO, that CR is almost no-man's-land. Pretty high for pump gas, and not high enough to take advantage of running high octane fuel. If you are planning race fuel, consider more CR (mill the heads).
