    What size motor? compression? thru transom exhaust or headers?

    I ran a set of 450's on a 454 HO motor producing 425hp for years on the the river. It was the cats meow for starting well and cruising fuel mileage. It ran great. I'd do the same thing again if I were to have the motor. For larger stuff go to a set of 750s or bigger. I have a 540 with two 950's now for my river cruiser. Had them done by C&J carbs. Just depends on what you want to do. I'd avoid a set of 660's.

    everyone loves those 660 center squirters, they are fuel hogs, but we dont build power with fuel economy in mind, just dont run out to far from the ramp.
