AWB...yeah that's about right (.500-.550) by my my measure too. My cam is only .570 lift (.552 w/lash)

Ryan's Stage 2 job will be perfect for what I need (the E's are also a little better under the curve) to get me safely in the 5 zone....plus give the motor the extra wind-out RPM on the top end to run my gears (4.56) in the quarter.
