Looks like I will drill holes into the intake manifold and run hoses from there to the carb. I found a K&N air filter that fits the Beam T502 carb. First and second stage pressure regulators are on the way (3000 psi to 100 psi, then 100 psi to slightly negative pressure).

Using used parts, I expect the total to be under $600 and have a 1.5 year payback. Plus it's cleaner for the environment and the engine.
