Got the 'standard' newman cam in mine, just had me new engine mapped on an engine dyno and i don't mind sayin i was very impressed at how it made power all the way through the range! I didn't have steel rods so we had to cap it at 6,300rpm, but power was still climbing at that point. I haven't got the engine back in the car and running yet so i can't comment on how it drives on the road, but it certainly looks like it's gonna be good on paper! To be fair tho, the head had recieved some fairly extensive porting so the results might not be exactly the same in a standard car.
