Why do Cam manufacturers grind advance into their camshafts?
Here’s how it all comes together. The cam companies know that when it comes to choosing a camshaft, many enthusiasts tend to suffer from the “More is Better” theory of engine performance. The common approach is that if some additional lift and duration is good, then more is better.
When does a cam line up with the crankshaft?
When a cam is installed “straight-up,” the imaginary centerlines of the two shafts line up exactly. Advancing or retarding the cam pushes the centerline of the camshaft to one side or the other of the crankshaft centerline.
What kind of torque does a camshaft have?
Cruise RPM 1600-2200 Strong low & mid range torque, daily driving. Cruise RPM 2200-2700 Strong low & mid range torque, daily driving. Cruise RPM 2600-300. Most popular cam. 350-455. Works with stock parts. H-O Ent. Strong mid range torque, street & mild bracket.
What should the length of a camshaft be?
A cam with a duration of 240 degrees of higher will typically produce the most power from 3,500 to 7,000 rpm. But there’s more to camshaft selection than lift and duration.
When a cam is installed “straight-up,” the imaginary centerlines of the two shafts line up exactly. Advancing or retarding the cam pushes the centerline of the camshaft to one side or the other of the crankshaft centerline.
What should the compression be on a Crower camshaft?
Modifications that should accompany installation of these cams include small diameter tube headers, low restriction dual exhaust, aftermarket manifold, increased cfm carburetor and reworked or performance ignition. Increased compression (9.5:1) is recommended for maximum output.
What are the characteristics of high performance cams?
These profiles are designed to enhance throttle response and low end torque in vans, trucks, passenger cars and mild marine applications while delivering fuel efficient motoring. High vacuum, smooth idle and maximum efficiency are characteristics of these cams.
What’s the difference between stock and twin cam camshafts?
Each of the camshafts in our test offered measurable performance increases over the stock camshafts and each set of cams has a bit of its own personality.
