I am having trouble with a rich mixture at idle as described in my earlier post. My engine has basically a stock cam in it and I'm sure it's not in need of a HV pump. I Emailed Edelbrock and they advised me that I should have no more than 6 psi fuel pressure. I have a Holley High Volume mechanical pump that claims 80 gph and a 7.5 psi shutoff pressure. What's your thoughts, would this pump just push the fuel through the needle valve and cause a rich condition? Almost every pump that I see in the mags puts out more than 6 psi. None of the few that I see that push 6 psi are chrome....gotta have chrome!
