Web Cam Type 1 Camshaft, Grind 226, 1.4 or 1.5 Rockers, 00-302 is designed for 1.4 and 1.5 rockers, and it's specs are .610" Valve Lift with 1.5 Rockers, 304 degrees of advertised duration, and 278 degrees of duration at .050" checking clearance.OK, there is no kidding anymore, this is a RACE CAMSHAFT! Valvetrain must be in good shape for this cam, we feel you can't even use VW Dual Springs, you are in the realm of Chevy Springs and wicked RPMs! We feel that you need at least 11:1 compression, and now are you at the point where instead of running better with more headwork and carburetion, it will simply run like #$()*& if you don't have it!
Powerband won't even start until 4000RPMs
Due to the Valve Lift you must have Chevy Springs, and you'll have Ratio Rockers (Bolt On Shafts).
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.
