Looking for some aluminum flywheel technical advise if possible please. The old school type aluminum flywheels typically had their brand and identity showing in the rear recess area so they were obviously not machined from a billet. My question is, were they a forged aluminum blank or a casting, and also whether anyone know what the aluminum alloy specifications were. I know that this is an "out there" request but I'm counting on the HAMB's diverse wealth of knowledge. Thanks in advance.
