Your max rpm for your big block????

hey....you never told us how big...your big block is....more importantly...what stroke you dealin' with?......i can feel in the pedal the difference between my 426 (std 3.75 stroke) and my 472 (4.15 stroke)....no more strokers for the street for me....I like the crispier revin' 426 over em' all...more than enough to twist the big drag radials.
