The bh 16 may be comming apart. An the question rises what could I put this drivetrain in? 415ci sbc aprox. 475 hp @ the crank maited to a blackhawk drive with 30" props. The boat that it goes in needs to run rough water, and get as close to 80mph as possible. Some of my first thoughts would be a retired svl race boat like a Extreme or Phantom. Lite boats, stepped hulls, could one of these be fast enough? Some of my other choices would be a 24 stepped Superboat or their 30 y2k. Another was a 21 Sutphen, 20 Cig, or possibly a 21 mtr Cougar or Eliminator 21 daytona. The last two would run but rough water? Last tought was to sell engine, buy 22 classic and build a 540 bbc 675 or so hp and bolt on the bh. Anyother ideas or thoughts would be great.
