We have sold via mail order, , and or installed many of this Comp Cams billet roller version with , so far, 100 % success rate.
In our opinion, the 206-206 grind we use is as big a cam that is needed to easily propel any properly recipied production blocked T/R far beyond the safe stress / RPM level we have chosen to apply to it.
It idles smoother than the stock cam, one of the quietest aftermarket faster ramp cams we have seen or heard, and is virtually invisible untill you mash the gas pedal.
It's a bit pricey, but in our opinion, when you considder it's perfect streetability and WOT performance potential, it's well worth it.
Once you enter the Stage motor catagory, where it's higher RPM levels are more forgiving, a more agressive cam grind can be considdered.
