Does anyone have any experience on, or know anything about the marine big blocks? I have a chance to buy a recently professionally rebuilt marine 383 at a reasonable price. The owner believes that it is a conventional, not backward rotation. I am wondering about compression ratio, forged pistons?, cam - solid or hydraulic (and three bolt I believe)? Heads - they are rebuilt, but are they like some of the oddball motorhome heads? Are they basically automotive blocks? I wont have a chance to see it and inspect it for a couple of weeks, just looking for info...
