SELECTING A CAMSHAFT
The intake closing point relative to bottom center listed in the table can be used as a
general indicator for the shape of the torque curve. Earlier intake closing values will
result in higher torque at low engine speeds (along with lower horsepower at higher
engine speeds). Later intake values will result in higher horsepower at high engine
speeds (along with lower torque at low engine speeds).
Intake Closing
(deg ABDC)
Less than 30° Early intake closing indicates a low speed torque cam.
30° – 50° Medium intake closing indicates a mid-range torque cam.
Greater than 50° Late intake closing indicates a high speed power cam.
Intake closing values are just one indicator of the shape of the torque curve. Camshaft
lift and duration along with the cylinder head‘s port size and flow, engine displacement,
compression ratio, and throttle size also play a roll in the shape of the torque curve.
