Hey Chris, I need that little fellow in my shop for a few weeks, hmmmm ... hardwood ply transom, sandwiched and overlayed with Kevlar mat, ply bonded stringers, hardwood ply floor, injected foam, 2000 model 5.7 Vortec (sittin in my garage ) bored .060, flat pistons, aluminum exhaust manifolds, polished 600cfm Edlebrock Performer carb & aluminum intake, custom camshaft, Alpha One Mercruiser drive, 1.47 ratio, raised 2 1/2 inches, and I'd loan you my prop if you will include me in your insurance policy ... I'd speculate a speed in the high 70's[/b
