I have a hyd roller cam for LT1. It is used and has about 2K miles. Specs are below and I was asked by the person who ground it not to mention his name for proprietary reason I guess but it is from a very reputable person. Price will probably be in the $275 range. Paid $350 new. The reason it is not for sale yet is because it is down at the machine shop where the motor was tore down and I dont know when Ill be able to pick it up yet.
