A Slice of Wedge

The camshaft is key to a good finish, and Nelson has chosen to consult with Crower for the right part. After seeing Crower's strong finish in last year's competition, we can understand Nelson's choice, but does the fact that the competitive Crowers are once again entered in the 2003 Challenge make a difference to Tom? Apparently not, as he has complete faith in Crower's advice, and Nelson has offered plenty of input toward his own profile grind. "This cam is extremely fast; even faster than some roller profiles. It's at 260 degrees at .050-inch of lift, and total duration is only 290. That's really snapping the valve open quickly, which I feel is key." The specs on the grind Nelson will begin testing with are .575-inch lift with the aforementioned 290 degrees of duration, .552-inch of lift on the exhaust side (with 282 total degrees of duration, and an equally-aggressive 262 degrees at .050-inch). The lobe centerline is at 104 degrees. The lifters will be Crower's solid flat tappets. View Related Article
