Edelbrock Performance Camshafts- Cam Card Locator

Performance Camshafts and Lifter Kits by Edelbrock
Edelbrock camshafts are matched to Edelbrock Total Power Package components for proven performance, taking the guesswork out of camshaft selection. They are compatible with OEM or Edelbrock hydraulic roller tappets which reduce friction, virtually eliminate break-in problems, and permit higher valve velocities for increased performance.

We are proud to announce the all new Camshaft cam card locator. Please type in the part number of your desired Performance Camshaft into the search field below. Proper search terms are as follows (2102, 5082, 7122).

CAM FEATURES: This camshaft works great when matched with Victor Jr. intake manifold #2902 and E-CNC cylinder heads #79559; this combo produces 676 HP / 649 ft.-lbs. of torque. Not for 1965-66 B/B Chevys requiring a grooved rear cam journal.
INSTALLATION NOTES: Use Edelbrock Performer-Link Timing Chain and Gear Set #7810 or Accu-Drive gear drive #7891. Do not use late model timing chain and gear sets that are designed for emission-controlled engines. These timing sets are machined in a retarded position and are not recommended for this camshaft installation. Edelbrock Timing Sets feature three keyways for specified timing selection. Use "0" position for most applications.
 
Footnote 1: Use with high stall torque converter only.
Footnote 2: Do not use dual valve springs. Use recommended valve springs with closed pressure of 120-130 lbs., open pressure of 320-340 lbs, and max lift of .700".
Footnote 3: Use only stock ratio rocker arms.
