Axle is the GX code 3.08 it was born with. Original heads / intake, AT, and a correct replacement Quad from the mid-70s, so compression should be close to what it was made to run on.
Howards website confirms that the -68 cam needs upgraded springs from stock. I'm going to call them and ask for a recc on what kind to use.
