My question is, if I switch to the XR270HR roller lifter cam, would I get the same results. The XR270HR is .495 I and.502 E with 1.5 rocker arms.

Which is the better cam for low rpm torque? Or is there a better cam than these 2 for bottom end torque?

Would someone care to tell me what the ideal build would be for bottom end torque? I figure if I have the torque, horsepower and performance would take of themselves.
A hyd. roller cam is always going to make a lot more torque.
This is due mainly because of the much stepper ramp rates on the hyd. roller cam compared to the hyd. cam.
Yes,it is true with the 1.6 ratio rocker arms you may cause more guide wear and the rocker arm stud gets loaded up more.
