Years ago then Chrysler CEO Tom LaSorta said that he had asked the engineering team to investigate what fuel economy improvement would be had if the then non-variable camshaft profiles were optimized for economy rather than peak horsepower.

The answer came back six percent according to LaSorta.

I wonder what the max torque in the 1400 to 2400 rpm range would be on a max economy camshaft?

What does Delta or Bullet charge to regrind a Magnum camshaft?
