A stroker better at the very least add an additional 70-75 hp, if not the expenditure is pointless and not very wise.

I think a big reason a typical Mopar small block stroker only picks up roughly 3 or maybe a bit more all things being the same type deal is because the heads used most of the time become a more noticeable liability on the extra inches.
look at even the old IHRA 900 inch mountain motors. They were, if memory serves, about 3 tenths quicker than a 500 non mountain motor deal. I think both shared the same head, didn’t they :realcrazy: crazy….
