Web Cam Type 1 Camshaft, Grind 163, 1.1 or 1.25 Rockers, 00-212 is designed for 1.1 and 1.25 rockers, and it's specs are .422" Valve Lift with 1.1 Rockers, 284 degrees of advertised duration, and 249 degrees of duration at .050" checking clearance.This is one of Web Cams best grinds, it's between the Engle 110 and 120. This cam REALLY comes alive with 1.25 or 1.3:1 rocker arms, and doesn't beat up the valve train! It has a broad power range for small and medium displacement street, off-road, or turbo engines, especially with Kadrons or other dual 1bbl carbs, OR center mounted 2bbl carburetors.
We had one customer that used this cam as follows. L3 heads, 9:1 CR, 1.25 rockers on the intake, 1.1s on the exhaust, 32mm venturis, 1 3/8" merged header, and made over 120hp!
This cam works best with mild head work, especially if larger valves are used. Expect a power band from 1300 to 5500 RPMs, the more head work and carburetion the better the top end will be.
You can get by with HD Single Valve springs and Bolt On Rocker Shafts, but will need dual springs with 1.25 rockers. Use a compression ratio of 8.5-9:1
If you choose to use this cam with 1.25 rockers, you will extend the top end to 5800.
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.
