CAMSHAFTS

BC high performance camshafts are ground on state-of-the-art CNC cam grinders to insure accuracy and tolerances to within .02mm. Every BC camshaft profile has been prototyped and dyno tested for proven horsepower results prior to being placed into mass production. By grinding cores in high volume, Brian Crower, Inc. is able to pass the cost savings on to the end user. Quality at an affordable price. All BC cams are checked on a high speed, sub-micron accuracy measuring gauge. The Adcole Camshaft Measuring System uses individual measuring heads for each cam journal and cam lobe, with .01 micron resolution, taking one datum point each 1/10th of a degree or 3,600 data points per revolution. Measuring camshafts for rise error and chattermark detection, this model can measure 200 parts per hour.

Big lift and duration spec focuses on top end power. Requires BC spring/retainer kit. ECU and cylinder head work will enhance overall performance. Due to high lobe lift, it is mandatory that you change the valve guides and use BC valve seals. Failure to do so will result in retainer to guide contact causing damage to the head and/or cams.
