no, just not sure if you had to have merc, and if you were looking at aftermarket, to buy in europe or buy them here.
plenty of builders here can do a 502block w/ 450hp.

The Magnum That Mel is finishing up is a 1976,27 Magnum Maltese with 383's and Bravo's

Additional photos...it runs in the mid 70,s...don't even have it dialed in. Bud

can you find for me 2x502 (450hp)?

Two 454 cu.in. Chevrolet LS-6 motors, single 850 Holleys. Glenwood log exhaust manifolds, with custom tail pipes. Turned 27" Mirage Props 5200/5300 rpms. The TRS drives are on 32" centers.


Here ya go...

A few more pictures for you, these were taken three years ago.

was it a smallblock boat with 32" centers originally?

Scrich, check with JCPerf on this site.
He's located in long island, NY.
Built my engine for my old boat.
There may be others on this site to do it too, maybe for less.
Post in the general forum for what you are looking for.
My guess is you'll be looking at 15K each.
You may also want to try Laz Mesa of Mesa Balancing in south Florida.

Federico: What stern drives are you planning on running on the boat is a big question??????? I presume you have the TRS drives if you were running the Mercruiser 330`s. If so and you intend to stay with TRS you should have the transmissions rebuilt and modified for the bigger horsepower.
That`s why I suggested the Bravo drives etc. in my original reply to you. So it gets down to if you are replacing the complete engine pkg. or just the engines. If it is just the engines you will not need the bellhousings etc. as you will use your TRS setup, and have a direct replacement. Good Luck
