Re: 460 marine bellhousing?/dyno?
There are several variations of bellhousing for Ford marine applications, some of which use different mounting points (to the boat's stringers or to the jet pump housing) and some that bolt to/accept a velvet drive transmission, etc.
Stick with a bellhousing that will accomodate a Ford starter at the 460's normal mounting location, because the reverse mount (and thereby reverse rotation) starter motors are very pricey...even just to rebuild one. It's so bad, in fact, that guys out here are remachining their revers-rotation top mount belhousings to accept AC Delco GM starters (since those GM starters are already normally mounted along the trans and not along the engine block and spin "reverse rotation" by virtue of their intended design).
This, of course, assumes you don't go elsewhere for your pulls, which it sounds as though maybe you should.
