tune up specs 72 bbc

Hello,
I am looking for the original tune up specs for my 72, it has a 400 bbc aand a 400 tranny. I have recently added an HEI. I currenly have it set at 10 degres BDC, @ 650 RPM. I am also replacing the plugs which I am planning on gapping at .045.

Any details will be appreciated. I did check the FAQ but could not find what I am looking for

Regards,

Mike
