On a Formula 292 (current hull design) which power plants are the better candidate for pro or whipple chargers - the 350Mag or the 6.2's?

Pat McPherson

I don't have a technical answer for you, but I would say the 350...
A lot less $$ to replace one when it blows up.

Good point!

There is not much difference in these engines. They share many of the same parts.

the 6.2 is a 377. go with the cubic inches...

I believe the 6.2 has a much stouter bottom end.

A buddy procharged his 6.2's in his 292 formula fast tech. These boats are a biatch to get on plane and worse after prochared beacuse of the larger props. You're going to want as much low end torgue as you can get. I think the 6.2 are tourqier(is that a word) than the 5.7. I'd go for the 6.2's

Thanks for the insight Caincando1

So your buddy wouldn't go that route again? Perhaps 377 Scorpions are the better choice normally aspirated.

if you procharge the 6.2 you will need an oil cooler and a larger oil pan. the 6.2 is really lacking in the oil pan area and has no oil cooler

I believe either are equil canidates, I don't know if the 6.2 is more "stout" in the bottom end, but I can tell you
that it's nothing but a destroked 400 and uses a 350
crankshaft. They are both well balanced engines, but
hp to $.....the 350 would be the better choice. In a procharged application you wouldn't notice much differance. I also agree, a larger oil cooler would be
a good idea, especially if you plan on running the boat hard.
