are you guys building your own, or gonna buy a crate motor ?

I think I'd call Summit Racing, they do crate motors, tell them what you're doing and ask for a 383 stroker done up as a marine engine, specify a block with 4-bolt mains - though I think all their strokers are done that way anyways - that would be the fastest best trip to that end result.
