Also noticed that you are running a carb spacer... Not sure what RPMs you are turning in that engine, but that will move up your intake range by 1000 RPM. So if you are not stalling at 2500... and are not cranking 7500 RPMs out of your engine, you are losing a bit there. The Performer RPMs range is 1500-6500 out of the box, if you aren't going out of that range, I'd leave out the spacer.
