current set up is a GM crate 350 with edelbrock 600cfm and JEGS brand air gap lookalike intake, bolted to the stock powerglide. no power brakes.

my question is… should i use my vacuum advance port to the HEI?

i have my PCV valve port hooked up and im going to connect the manifold vacuum port on the carb to the intake.

what do yall think?

yes, connect the vacuum advance port to the lowest port on the carburetor.

... and a PCV should always be used, it will connect to the 3/8" port on rear of carb.. ;)
