[cobred]

Greg, I would buy the parts you need through an fe builder on this site such as Keith Kraft. You can talk to him on the phone, explain to him what you would like to use and he can give you his advise based on experience. I bought my cam, lifters and pushrods from him. He had Comp. cams grind me the solid cam to his specs and my wants and it works great. I checked the pushrod, rocker geometry and all was fine the first time.
Another suggestion, use a good rocker setup the first time, a few hundred dollars extra spent in this area is good insurance when you figure the cost of building a Cobra. I have the Erson roller set and its trouble free.
