Vaccum line question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

This is how my vaccum lines run now.

Brake booster and vaccum ball to back of intake.

Dist advance to ported on carb and tranny to full on carb.

Is this the best set up? Looks like I have two open ports on tha tree in the back of the manifold?

Thanks

The way I have mine is full port on carb to distributor (this varies person to person), the tranny and heater vacuum hose are to a T behind the carb on the intake then and a brake booster tied into the rear port on the carb.

booster = carb base

dizzy = ported on carb

trans = tree on intake rear

vac ball = tree on intake rear

One more thing is to make sure all your vacuum ports even the ones that are on your thermostat housing are hooked up or blocked off but on the housing if nothing ran to them then no problem.
