I agree. Would be good for (sport) cruiser's and thus if they build them well many, many hundreds of hrs before any top end rebuilds.

I'm really curious about it also. Could work well for my bowrider. I've requested pricing from a couple of places, should have it on Monday. Anyone know how strong the internals are? Good strong forged stuff like previous 454/502 Magnums?
