Where do you get these 454 420 hp marine motors???
What would the dock manners be like putting on one of these blowers???

Damn down size ur props and turn them at 5000 you'll prob gain

Isn't that pretty much what a 525SC is?

I bought some 502 "450hp" HO crate motors..........when they say 450hp they mean 450hp with the right set of accessories...........maybe. Mine dynoe'd closer to 418hp with a 850 holley.
