OK, the great camshaft debate!! I am currently in the process of putting in cams! I have WEB Cams 294 grind laying in the head.
Stock early bigport TViS engines ran a duration of 240 degrees with 7.56mm lift
Stock late smallport non TViS engines ran 232 degrees of duration with 7.1mm lift
WEB Cams 294 has a duration of 244 degrees of duration with 8.175mm of lift
I have at my disposal 3 cams of a 264 duration and lifts of 7.9mm, 8.1mm, and 8.35mm. Mike and I believe the WEB Cams will be adequate for our first race, but if anybody has a good reason why we should go beyond that now is the time to raise your voice above the crowd! I'll be installing the cams MONDAY, if you are happy with the 294 grind cams, great, if not, speak now or forever hold your peace!! Here are pics of the WEB Cams and adjustable sprockets planned for use.
