SCAT C35 Type 1 Camshaft, 1.1 or 1.25 Rockers, 20005 is designed for 1.1-1.25 rockers, and it's specs are .381" Cam Lift, .420"/1.1s and .476/1.25s, with 285 degrees of advertised duration, and 246 degrees of duration at .050", on a 108 Lobe Center.
This cam is similar to the Engle W110 grind; it will run like a bag-o-nails with the stock carburetor, so you have to upgrade to at LEAST dual 1bbl carbs, or a single 2bbl. But it's Velvety smooth with dual 2bbls! This cam requires HD Single Springs and Bolt On Rocker Shafts with 1.1 rockers. If you decide to step up to 1.25 rockers you MUST have dual springs! This is also compatible with stock Single Port (barely) or Dual Port Heads, and it works best with Compression from 8.0-8:5:1. Power band is from 1500 to 5000. |

Or the long clutch release arm.  I have one on mine with the kennedy stage 1, feels like stock.

don't take the wear off the bearing or the case, no matter how long the clutch arm is. if you don't know how to fix it, you might not know how it works.
