Hold on a second now....

A camshaft installed straight up means that it doesn't have any retard or advance in it at all. Comp Cams does grind most of their stuff 4 degrees advanced. You can adjust it with the timing set from there. Installing it straight up wouldn't be too far advanced....

Also, a "bushing kit" is a Chevy thing.....not a Ford thing.

Different engines need different amounts of timing. A 3500 rpm total ignition timing rpm is a band-aid for what's wrong, and in reality will make the car extremely lazy. Cobras need a 2500-2700 rpm total ignition timing rpm.
