220-230 at 0.050 and 110-112 degrees separation are good numbers to work from for almost all street applications.

My two cents,

Amen! Add my two cents, Glenn. I cringe whenever I hear "I want that lumpy idle" as the prime selection criterion for cam selection. I went that direction on a GTO back in the day, and it would go like a scalded cat - but was worthless around town and in traffic. The cam in my ZZ-430 clone is 218/228 @0.50 and 112 lobe separation. It idles like a charm at 750 RPM, and flat goes when I hit the loud pedal.

A good example of all pieces matched toward a common goal.

Yup - Tech, Jack and I are all on the same page here and we really want to see (and hear) a great build for you!

A friend of mine recently taught me a simple way to get that great sounding lopey idle on any motor, leave the choke on... And, it loads the motor up just as fast!
