I would go 4.375 bore/4.500 stroke for a reliable 540"



not that im arguing with you bob but I always thought the bigger arm would hurt longevity!

I dont wanna have to run the 572" setup and the indy 572-13 heads and a giant roller..... just not my thing.....



440-1's work just fine on a 572. (same bore????)
just a bit bigger roller?? or not even change cam when you get tired?? for the same money why not have the extra 44 inches now and not be pining for them later. Then when you want more it's valve springs and a bigger cam to unlock a tone of unused potential
