This is going to be another royal battle I can tell so maybe we should start a separate thread?

1) Pretty easy to tell a casting line on a crankshaft vs a forging line on a steel crankshaft. I have been dealing with Moldex Crankshaft and Kellogg for over 45 years. Give me a break. I have 5 forgings for the 366 Engines in my garage right now. I bought 15 of the things when Moldex was going to scrap them. Only owned 1 RA-IV SD Crank sold it to marty Palbykin for his Twin Turbo Engine. The other crank I worked on and sent the engine down the road.
2) So you need to do a bit more research on the RA-IV SD engine. I don't have to prove anything to you.

If you had asked Mack McKellar or Tom Nell these questions years ago they could tell you all about them.
