My 493 Indy head engine likes 24 base and 34 total all in at 2000 RPM. Is it a perfect street car? Probably not but then mine is an old school 10 second stick car so it drives like street/strip car. I'm gonna hook up an A/F meter this season to dial in my new cam and intake deal though. I have a mechanical Firecore distributor with no vacuum advance with a Howard's 260/264 solid cam.
