ok i just got a new cam ground to match my heads flow figures
306 duration and .530" lift with very aggressive opening ramp.
first time i have seen a a-series cam with over .480 lift. has anyone else used a cam with this much lift in an a-series

Mine has 509 but only because I run 1.65 roller rockers

We use lifts over 500 in our GT-2 L motors, but they don't pull very well below 5000. Now, 'very well' is a relative term, of course... they DO pull, but then you hit about 6500 and all hell breaks loose!!! And they pull well past 8.

My inlet valve lift is .4118 and i though mine was bad!!!!
It sucks under 3 grand but at like 3.5 and gets up and goes pretty well
I dont think id ever buy/put a lumpy cam in a daily driver again it sucks in traffic
