So I installed a 4160 750 Holly on my 350 yesterday, but I'm running into a few vacuum hose issues. I know where the dist. hose connects (it's clearly noted). TA Performance answered one of my questions by telling me I can attach the PCV valve hose from the very rear of the manifold into where the brake vacuum line would normally go. Also, the transmission vacuum hose has no where to go so I used a T connection and tapped into the dist. port. Should I do that? Any help ASAP will be greatly appreciated and will guarantee a get-out-of-jail-free card, if need so, from me.
Transmission should go directly to manifold. There should be a 1/8 npt (maybe 1/4, can't remember) port about 1 1/2 inches behind the carb. Thats where your Trans hooks up to. And, where are you gonna hook your brake vacuum to?
The brake vacuum goes from the booster to the intake behind the carb (passenger side). That's where TA said it should be hooked up, which it is. I guess I can look to see if there are additional ports in the intake to take advantage of. Actually, there is a port on the carb that is unused, which is where they (Holley) says a full manifold vacuum line is designated for, but that doesn't seem to be needed apparently with this set up. I'll try that one.
