How hard can i rev?

Are you sure about the weight of the car - my 68 2dr post weighs 3150 with a small block, back seat removed and 10gal aluminum fuel cell. My 2dr ht weighed in at 3350 in basic stock trim.
I agree with others - you limiting factor is the stock rods - over 6500 is definitely pushing the envelope - thus you are not going to get the full potential of the cam. the TC should flash to at least 35-4000 to get a good launch. anything below will tend to bog off the line (except with 26" tires - it won't bog, just spin)
At a conservative 575hp, 3450lbs, 30"tire,4.56gears it claculates out to this:
E.T.: 10.64 Seconds
Trap Speed: 132 MPH
Trap RPM: 6,724 RPM
If you are as light as you say it is you will be in the 9s. -and thats not bad, just scary :color:
