COMP Cams 31-409-3 Details

Ford 289-302 c.i. 8 cyl. 1963-1995

Very strong mid-range. Every day performance for stock exhaust.

Comp Cams 'Dual Energy' Hydraulic Flat Tappet Camshafts

Comp Cams Dual Energy camshaft's have a ''split-profile'' design (higher lift/duration on exhaust side). Designed for applications where a slight sacrifice in low end is acceptable for an increase in mid and upper range RPM horsepower. They may be used in conjunction with an exhaust system that is much more restrictive than the intake system. These cams should have no adverse effects on any power or vacuum accessories like power brakes or power steering. The idle quality of these cams are mild enough to run with air conditioning.

Features:
  • Similar to High Energy Cams but better at high RPM when coupled with headers because of added exhaust duration
  • Work great with most stock components
  • Very flat torque curve for great streetability
