I use a small solid roller from Comp Cams, XR286R, 248/254 duration, .576/.582 lift. I drive my car on the street a lot, and this cam in my combo makes a TON of torque and pulls well over 6500 RPM. I am going to be switching to something a little bigger in the near future (a little over 260° duration)....but cam selection really depends on what you want your car to do.
So which is it, race only, street, or a blend of both?
