My experience for the record the billet cams when you do finally get them are good quality. But! make sure Dale gets the timing right, he sent me a set with exhaust and inlet timing reversed which caused a valve to hit a piston and destroyed my motor. It cost me $3500 to rebuild.
Compensation from Dale a new set of cams that was it.
My mechanic dialed in the new set to HRC timing they seem fine, we have got about 141hp at rear wheel.
Bottom line, cams when dialed in correct good, customer service shit!
