Default WTB pistons 4.35 stroke deal

A long shot… looking for pistons in a 4.181 bore block and 4.350 stroke deal.. with 6.700 rods and .990 pins.

Any luck?

Thanks - Kris

No it’s not the same piston. The 4.25”x 6.800” combo piston would be down in the block .050” with your combo

Thanks for setting me straight… you’re right if the pin dimension is the same it’s still half a stroke at tdc.. => no free lunch
