subtract that off my .544 lift cam and Ive got didly squat! Less than a stock 5.0 cam! Which if you listen to my car sit and idle, it sounds like it has something more like a stock cam than what I really have. So with this info, Im going to check push rod length tomorrow, if I dont have the 6.750" length they say, Im going to stick them in and try that, that thing may really kick, that could be the little kink thats held me back for a year!

Nope .... the push rod length has nothing to do with lift unless you have non adjustable rocker arms and you have a ton of clearence that you shouldn't have ? It has to do with rocker geometry (where the rocker tip rides on the valve tip and at what angle) .... If the cam lobe moves a push rod a half inch on one end, it will move a half inch on the other end, reguardless of whether its 3 inches long or 3 miles long. All the push rod does is transfer the movement from the cam to the rocker arm.
