- Order number: EDL-2261
- Notes: This camshaft works great when matched with Victor Jr. intake manifold #2902 and Victor Jr. 24° cylinder heads #77485; this combo produces 611 HP / 573 ft.-lbs. of torque (Tested on a GM ZZ-502 shortblock). Not for 1965-66 B/B Chevys requiring a grooved rear cam journal.
Edelbrock Rollin' Thunder camshafts are designed to improve horsepower and torque, produce a great sounding performance idle and provide excellent vacuum at idle to support power accessories. Rollin' Thunder camshafts feature more aggressive lift profiles than possible with conventional flat-tappet hydraulic cams, without excessive valve overlap that can compromise low rpm drivability; reduced friction provided by roller tappets makes this combination of accelerated valve lift and reduced duration possible. Edelbrock Rollin' Thunder camshafts are performance-matched to Edelbrock Total Power Package components for proven performance.
