Advancing stock cam in a 360?

Speedy Pedi said
I built my 360 magnum stock bottom end and used 4 degrees cam advance with an HEI ignition engine fires off immediately. Set your spark plug gap to .45 to realize the benefit 45,000 volt of hotter spark. The cam advance will increase the cylinders dynamic compression according to David Vizard. I have my initial ignition timing set to 16 degrees at 800 rpm with no issues. According to Vizard the benefits are better power on the low end power with better drivability.

Thanks for the reply! Maybe I’ll use the 4° mark, maybe someone will say don’t. Maybe someone will say if I do, I’ll need to machine the everything, and recalibrate every piece of the engine with machine shop tools.
I’m not at ignition timing yet, but I will be looking to optimize that also since I had to put my tail between my legs with a cam swap.
