Erson Camshafts

Hi Paul,

Erson RV15M Dutra RDP
Power down low is hard to judge, but I'd say 1500, ends about 4100.
Dual Dutra Duals into 2-1/4" Head pipes, single 2-1/4" out.
500 cfm Carter AFB on an Offy.

There are probably some more questions you should take into account. The build is going to have a lot of effect on how a specific cam delivers.

What have you got for compression? What mods have you done? Include converter and rear gears.
What's your goal? How are you going to drive the car? What kind of terrain? Primarily highway or around town?
