Delta has 2 grinds for use SOHC guys. The 148 grind and the 2000 grind. 148 gives more low end/mid power with no idle problem, while the 2000 grind give mid/upper power. The 2000 grind does cause a lumpy idle and you'll need to adjust the idle speed in the ECU for those or you'll get a CEL or car that will just die. When I got mine done, cost me $203.70. See the attached link for more info on the Delta cams.
