Advancing stock cam in a 360?

Back in the 70s and 80s my buddy would advance the cam gear 1 tooth on stock non hp engines. Really seemed to perk them up. I’m thinking it was 8* or more. I’m sure someone will do the math. Kim
Using a 46 tooth cam gear and a 23 crank gear, 360 degrees/ 23t would be 15.6 crank shaft degrees OR 7.8 camshaft degrees. SO yup 8*
