Victor, You need to calculate intake valve closing point in your effective compression formula. The later you close the valve on the compression stroke the less swept volume you will have for your formula.
Changing from a stock turbo cam to an SC cam closes the valve later thus reducing the effective compression.
WydRyd, 7.5-1 works nicely with SC cams.
