Hey burnt68, any chance you have a pic of that. I don't see it on mine, but then again the holley site says not all have it. As far as spacer, there is one on it right now for clearance issue i had, but no port.

 

having some internet issues, not sure if this posted, sorry if it already has. Burnt68, any chance u have a pic of that port. I don't see, but Holley website says not all 4150's have it. Also, mine has a spacer currently, but no port.

 

I'd have to see a picture or drawing of what you're describing. Are the pcv and booster connected in series? If your only option is to connect them to the same vacuum source, it's better to have a tee at the manifold, then split off separately from there.

 

You got it dude. One vacuum source on intake has a hose to a splitter then two hoses off that (one to pcv, one to booster). Unless i can hook pcv into aircleaner or somwhere else since carb doesnt seem to have a port, this may be my only option. And if so, I think it would be atleast better to have the fitting on the intake with two nipples, than one nipple and a splitter inline off that hose (as it is now). What do you think? Ideas?

 

My thought about not daisy-chaining them together was so that you wouldn't take chances of getting any oil contamination near the brake booster. I would still want my booster getting full vacuum on it's own dedicated connection, even if you had to install a carb spacer with a vacuum port for the pcv, as already suggested.

 

Cool, thanks. Is there a torque spec for valve covers for my 350? I have the 4 bolt, not the center bolt.
