Hi guys, haven't been around for a while, but thought I might shed a little light on this engine for you. The 6.2 is 377 cubes and is Mercruisers attempt to get a little more torque out of a small block to move heavier boats. Since the 7.4 (454) isn't being made any more they needed a way to get that torque and yet have a lighter, smaller package.
I don't know a whole lot about them as I worked in the office end of the marina business, as opposed to turning wrenches, but I do know the Techs had respect for them and felt they were pretty good engines. They share a lot of other 5.7 components, but the fuel system, intake, etc is different to get better flow.
I am running a 5.7 marine engine in my 23 and it is virtually identical to what you would get in a Chevy car or truck, except for a few minor differences. The cam profile runs out of steam at 5,000 rpms, and the head gaskets and freeze plugs are corrosion resistant for salt water use.
To get back to your original question, would one of these 6.2's be good for a hot rod?...........I guess it could be made to work, but it is not the 383 stroker it appears to be. A better value would be to simply add a stroker kit to a 5.7. Cost would be another factor and because the 6.2's haven't been out there for lots of years they still would bring good money, if you could find one, far more than you would have in building a 383 from scratch.
I know this wasn't a ton of info, but hope it helps a little.
