Does my 451 have to small of a cam?

Dart273,I never have owned a computer or a hotrod in my life ,so iam sorry if I fall short of your expectations! I will get pics. Posted ASAP. The reason I bought this "RIG" as you call it,was because I thought it has potential.With the great help from most of you I WILL know what iam looking at when asked. Now,if you ever need help setting up a M40A2 for a 1500yrd. Center shot, call me , that's what USMC. Trained me to be a EXPERT at.

ok understandable but try to be more discriptive. I still dont believe that the cam was your problem. You have to fix the other stuff to know for sure. Keep it simple. The reason people ask for photos and more information is because there trying to help. But its tough to troubleshoot over the computer. Which is why we ask for the information. What you should do is assume that this motor was built correctly and try to figure out why its not running right.

Whats timing set at? Remove that spacer. Whats your compression ratio? Once you put it all back together and it still runs like a turd that work would have been for nothing. Did you remove the lifters as well? Hopefully you marked there location if you are resuing them. People DO want to help but need more input from the guy needing help to make be able to tell you what might be going on.
