What is your fuel pump output volume? If it will produce at least a pint of fuel at idle speed in 30 seconds, don't worry about fuel pressure. You won't be able to send PM's until you have made at least 5 posts- - - -keep talking. Check out the power valve in your carburetor- - - -it looks like you need one with a stiffer spring that will open up and bypass the main jets at a higher manifold vacuum. The carb is going lean at part throttle and causing the bog. Opening the power valve sooner and MAYBE going to a slightly larger main jet will solve the problem, but I'd tinker with the power valve first. About 30 years of round track racing with a Holley carb taught me a few tuning tricks, and power valve swaps make a huge difference when transitioning from closed to open throttle.
