Can anybody with an F303 cam tell me what you vaccum is at idle. I really don't think that I have a leak, but only registering about 16 at idle........is the normal?
I dont have an F cam but 16" at idle sounds pretty good to me.I wouldn't be complaining. I get 9-10" at a 950 rpm idle with my camshaft, but its a "tad" bigger than an F cam
