I was wondering what kind of speeds people are getting out of the fastech 271 with a stock 500 or 525. Thanks, Jeff Wurl

Not sure with those engines, but I know with the 496 h.o. top end is in the 60 to 62 range, so an educated guess is gonna say 65 to 70 depending on alot of variables. A friend of mine had on and traded it on a Donzi 28Zx with a 525 and it pulls low to mid 70's(and he's not much of a pilot)
