I'm leaning towards a whipple setup on my current motor , after seeing the replies . Does anyone know if there are any clearance issues with the pulleys and the bulkhead on the 27 ?
I found another motor but it is not a marine engine , it's a 572 BB chevy crate motor for $ 4000.00 only seen 1200 miles in a street rod . Supposedly 650 hp with a single carb . I don't know if this would work in a boat . Not sure what changes it would require for marine use ?

All the Blue HP Merc engines are assembled by hand, and are Balanced and Blueprinted, and have better internal parts, ie- as in JE pistons in the 500 series Blue Engines. They are a special piston manufactured for Merc by JE. They also have better heads and bigger valves and better exhaust than the Black engines, along with a few other differences.
All the Black Merc engines are more or less a crate type engine. Not that thats bad, just not more of a custom precision engine as the Blue motors.

So now I'm wondering again ... will my black motor hold together with the added hp from the whipple or will I be sacrificing reliability ?
In the long run , I'm wondering if I'm better off taking the 572 and having it redone with all the high end internals and specs for marine use . I would guess it could produce some impressive hp #s with the right parts . Building it up with proper tolerances for marine use would eliminate the need for the closed cooling system . Anyone with some technical know how on this subject ?
