Web Cam Type 1 Camshaft, Grind 86B, 1.4 or 1.5 Rockers, 00-102 is designed for 1.4 and 1.5 rockers, and it's specs are .575" Valve Lift with 1.5 Rockers, 300 degrees of advertised duration, and 260 degrees of duration at .050" checking clearance.This is Web Cam's most popular "ratio rocker" specific grind, it drives like an Engle 120 but keep pulling! Valvetrain is not "Harsh", but not easy either. This cam requires 9-9.5:1 compression, and the more headwork and carburetion the better it will run. Nice 800RPM idle with dual 2bbls.
This cam works best lots of headwork, 40x35mm or larger. Expect a powerband from 3000 to 7000 RPMs, the more headwork and carburetion the better the top end will be.
Due to the Valve Lift you must have Dual Springs, and you'll have Ratio Rockers (Bolt On Shafts). This is the biggest cam you can NOT use Straight Cut gears with, even then it's recommended if not required.
Lobe Center: The proper term is really "Lobe Separation Angle", but people more recognize "Lobe Center" so that's the term we have used here. Lobe Center is a VERY complex topic, generally speaking a smaller (Narrower) Lobe Center will improve low end power at the expense of top end, and a Wider Lobe Center will do the opposite. Of course, duration does the same (more duration helps top end at the expense of low end), but it's just another way to further refine your power. If you do not know what Lobe Center to choose, the VW Standard is "108 Degrees" and you won't go wrong with that (if you didn't know, we would send you "108 Lobe Center").
We do offer other Lobe Centers for guys that have researched the topic enough, and make these options available to those that want them.
CAM CLEARANCING: Select the Cam Clearancing option for stroker crank on long stroke engines! It's needed on all 82mm or longer strokes, and SOME 78+mm crank/rod combos (VW or Porsche journals). It depends on the size of the big end of the connecting rod, but USUALLY the bigger the rod journal the bigger the big end of the rod. Generally speaking H-beam rods have a smaller "Big End" than I-beam rods do, but the only way to know is to check. If you aren't sure, just pay up for the "Cam Clearancing" option for the most room on your engine build.
