best cam 06 dyna
I have talked to Andrews, Dave Mackie, Harley Davidson techs, and Bob Woods. The cams each of them recommended for me were as follows
Andrews 54H
Dave Mackie TC575
Screamin Eagle SE211
Screamin Eagle SE257
Woods TW-9-6
Red Shift 577TC
Intake Open BTDC is the number of degrees before top dead center that the intake valve opens on the exhaust stroke.Intake Close ABDC is the number of degrees after bottom dead center that the intake valve closes on the compression stroke.Exhaust Open BBDC is the number of degrees before bottom dead center the exhaust valve opens on the power stroke.Exhaust Close ATDC is the number of degree after top dead center the exhaust valve closes on the intake stroke.Intake Duration is the number of degrees the intake valve stays open as measured at .053 inches of lifter lift.Exhaust Duration is the number of degrees the exhaust valve stays open as measured at .053 inches of lifter lift.Intake Lift is the maximum intake valve lift in inches.Exhaust Lift is the maximum exhaust valve lift in inches.Intake Lift TDC is the intake lift in inches at TDC.Exhaust Lift TDC is the exhaust lift in inches at TDC.As a general rule, cams with 220-235 degrees of duration tend to produce good low end torque. Cams with 235-250 degrees
of duration tend to work best in the mid-ranges and cams over 260 degrees work best for top end power. Camshaft overlap
duration less than 30 degrees tends to produce good low end power. Lobe Separation Angles (LSA) of 100-103 degrees tend
to produce power at the low end.Cams with valve lifts .500 inches and under, with a duration under 250 degrees are generally considered bolt-in. Cams over .500
inches lift and 250 degrees duration require increased compression and head work to work best.
