My 63 is a 99% street car as its a 493 with Indy EZ heads. Its at 10.6 comp and has good .045 quench. It likes about 21 initial and 36 total. No vacuum advance as I got a great deal on a Mallory race dist with no vacuum advance. And I have full advance by 1800 rpm. The car runs awesome like that as it has great driveability. Ron
