Find a junk yard carb w/ air cleaner, with a hand choke linkage.Ford300 pick up, or a Dodge /6.
I did headers and dual and an intake to no avail for top end. So I put on qa vacuum guage and ran it at full throttle, full speed. It made 2" of vacuum. Expectation was 1/2". Bigger carb at that point made 20% more horsepower.
