wow used to be i could tell why a mc91 piston has issues in an older motor but seems that memory is stored deep?
anyway i think the 91 piston might work in an old motor but an old piston won't work in a new motor because it kills the extra ports.
if you just want to run the correct piston with thin rings but oversize i probably can help you out.
i have early oversizes that would suit your project better?
i'd be open to a trade as mc91 oversizes are getting low in my pile.
