I am very happy with my 280X4 cam. My rappy revs up very quick and man does it pull.

I launch about 1/2 throttle in first gear and let her rip. It leaves the line harder then the stage two hot cam.

End of summer I'm going to switch to the 13.5:1 Ross on my 686. But I'm going to get a good summer out of the 11:1 before switching to the higher compression, and yes I have already switched my rod and had it balenced.
