ok, maybe some help can come from here. I run a Chevy 427 bored 60 over. Crane "BlueprintFactory 425hp 427" cam, 4150 Holley. 12:1 Janns. I had problems with sputtering and flatspots last year, so took out the powervalves and installed plugs. Now I have been killing myself trying to get the right jet setup. I have been told everything from low 70's to high 80's.
Then, when I time the motor, it will only run in the 36 to 38 degree range. Does this sound like cam timing? I am lucky to get 4400 RPM with an A impeller in an A.T. jet.
