31ss, 365's,24" B1's, 68.3 gps
got 69.1 once
502's should be in the mid 70's
Sounds more like 330s'.

bn

Are they carb or fuel injected 502's?

rssteiny

415 hp carb.

rssteiny

what props are you running on a 31 and with what power.

Are you sure about the 415 Carb? The fuel injected 502 is 415hp and the carb 502 is 390hp, unless the carb motors are hopped up a bit.

With 502 MPI's (415hp) a 31 will do about 72 - 73 mph.

I am currently running 496 Mags with 26P Bravo's.
