Hello, I just bought a 383 crate engine and it came with a Demon 750 vac. sec. carburetor and an MSD hei ignition 4 pin with vacuum canister. Ive never dealt with a barry grant before and I noticed there are 2 vacuum hook up's on the passenger side of the carb. I am assuming it would be ok to hook the vacuum hose up to either one of them but I am not certain. Is this correct?
