I'm feeling beter now. I've just check the web site where I bought this. Ok- it was from Tom Langdon. I bought his "bulldog" cam. Duration 254/264. In his tec tips he recommends using hydraulic lifters with this set up. So I got just what I needed. I'll now need longer pushrods, but I was going to buy new ones anyway as two of the origionals were bad. Tom also has a tip for nisy lifters which I have a couple of questions about as to if I should do what he describes before I install the new lifters or wait to see if I have a problem.
