Cams How do you choose one?

Seems like the recommended Bullet cam specs are very similar to the Summit 1789 , but with a hair more exhaust duration. Summit Racing® Camshafts SUM-1789

That’s because these professionals know how to grind/spec a mild cam that will see a lot of time in the street!
That kind of cam will live half way to forever and get decent mileage while providing a reasonable increase in power. Summit cams are (or were) ground by Crane. Another ICON in cams.
