This isn't the cam Marvin had in mind for this application. Blair brought him a Schneider Racing hydraulic roller cam, grind number 284-RH. What this means in actual numbers is 284/284 running duration, a lobe lift of .340/.340 inch, and valve lift of .544/.544 inch with lobe centers at 112 degrees. This is an aggressive camshaft designed to do its best work at 3,500-5,000 rpm, where peak torque is expected to occur. While this makes sense on a racetrack, it doesn't hold much weight on the street. Idle quality and driveability will be compromised. At high rpm, get out of the way!
