Until I (we) get Mr. Furback's response re checking of his L78 balancer markings, may I summarize a couple of things?
The casting number 3870325 punched on the inner section of the balancer was used for many applications and cannot, repeat cannot in fact be used to identify a balancer specific to an engine's advertised HP rating(s).

Now, the numbers 9623 on the outer ring mean exactly what?? Are these numbers an abbreviation for 3879623 which in fact would make it good for 67 - 69 L88 and 69 ZL-1 engines.. ??

The code G2 F means ??

Thanks!
