So it seems that you are saying that you cannot make a better cam profile than a stock "H" cam specs, & if you do make a different pattern camshaft it cannot work?

You do not need to "race" your car to have & use a better performing camshaft.
Could have a custom camshaft that makes better mileage that performs better than stock.

The TheSilverBuick guy here on this BB has installed the "H" camshaft & seems displeased with the output as it cannot reach the peak RPM that Pontiac says it can make power to.
He is using a better fuel distribution Megasquirt, EFI, distributer less ignition, yada, yada yada.
Are they supposed to pull to 6500 RPM?

Good luck with your search.
