Well, all are 1.6 ratio...
Stock Cam specs:250/264 duration with 385/401 lift 33 degree overlap
At what lift? and what centerline? Not sure...
Crane 2030 specs:Advertised is 260/264, at .050 is 204/208, lift is 458/467
on a 114 centerline and 34 degree overlap.
Mopar cam is the same lift and duration but ground on a 112 centerline.
Crane708HR00001 is at .050 214/220 duration with 520/531 lift on a 112 or 106
centerline, no overlap spec.
1.7 roller rockers with the 2030 will net the lift to 486/496 (good choice).
Question
is, Crane 2030 114 or Mopar 112 grind better for normally aspirated motors?
The 112 develops more cylinder pressure at lower rpms (torque). Is this for
Dragstrip Plus program or Quarter Jr.?
