- Dec 6, 2004hi Dave,
the block and heads are cast iron. I'm pretty satisfied its a 74 472 with
the flat top pistons. Everything else appears to be stock.

The 472 rods are 6.75" long, and wrist pins are 1".
What's the bore/stroke? 425/472/500 valves are apx 2"/1.625".
Rod journal is 2.5". I'm not well read on casting #, or the 368"
engines. Are the block/heads cast iron?
