I actually have a book that shows dyno charts from each cam individually, when I get home I will have to upload it! I have the NPI 268h's in my PI heads and I love them... Beautiful rumble and totally daily drivable!
What Type.of Cam do i need?

These tests were run on an engine dyno with a 4.6 with ported heads from total engine airflow, PI Intake, accufab 75 mm throttle body and elbow, and hooker headers. For me, I knew the 262s would be the best power wise, as there are no power losses down low and peak horsepower difference between the 262 and the most extreme 278s was only about 3% (and it came way up at 6100 rpm vs 5900), however I chose the 268s as I wanted the "mildest" cam that still had a little rumble.
