The Engine I'm selling is a legal Low Compression 415hp 1963 Engine. Also, I think you could get away with running '63 carbs on a '64, I don't know why you would, but, given the state of "stock" they'd probably let you go since the carbs are too small ! One more piece of info ....a little birdie told me that the '63 ('63 only) 415hp engine will be 405HP in 2011.

The 63 415 HP has been 405 HP in IHRA for a couple of years now. Must run the smaller carb's on the 63's and the larger carb's on the 64's in IHRA. Who knows what kind of *&^@# NHRA allows these days.
