Web Cam Type 1 Camshaft, Grind 111, 1.1 Rockers, 00-602 is designed for 1.1 rockers, and it's specs are .476/476" Valve Lift with 1.1 Rockers, 272/272 degrees of advertised duration, and 238/238 degrees of duration at .050" checking clearance.We refer to this cam as the "Super Torquer" cam, it the most torque possible for any cam in the 600-4000 RPM Range, regardless of carburetion.
This cam is "violent" on the valvetrain, don't expect more than around 5000 miles out of the valvetrain (it's similar to the Engle VZ Series in that regard). Do not even THINK of running rockers bigger than 1.1:1 with it either! Expect a powerband from idle to 5000 RPMs, the more headwork and carburetion the better the top end will be.
You MUST run Dual Springs and Bolt On Shafts with this cam due to the aggressive profile. Use a compression ratio of ~8-8.5:1.
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 offer a range of Lobe Center options for guys that have researched the topic thoroughly, and want to order a cam with a specialty configuration.
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.
