Holley Carb problem

You also have a terribly mismatched intake manifold. BUt I don't think that's what the trouble is.

Get a real vacuum gauge and get some readings and go from there. You might not have the vacuum that "mystery gauge" is showing.

Oh and "RV cam" covers a lot of territory. Specifics would be helpful. Even a description of the idle.....a video with good audio perhaps? This IS 2015 after all.

I will be picking up a vacuum gauge ASAP, and i would have included more details if i had them sorry, I ended up buying this rolling block from a well known mopar guy in the area to get the car on the road this summer while i spend time building a 360 how i want, all he knew is it had an aftermarket cam, got it from a buddy, i took the pan off before installing the motor to give it a look over and saw it had aftermarket pistons but dont know specs, just .030 over. i decided to just bolt on the parts i already had with plans of keeping an eye out for better heads to swap on this summer, then move over to my future build when ready. anyways i remember that when doing timing it backfired through the carb a couple times and I just tested the PV, in park at idle i could turn the a/f screws all the way in and the motor did not die, if i read things right that would indicate a blown PV yes?
