New carb - No vacuum ports ???
Well I got my car running today. I went to hookup the PCV and Evap and suddenly realized that I had none of the larger ports at the base of the carb. The only port I have is above the throttle blade and is for a vacuum advance dizzy. I'm going to T that into my dizzy and lockup kit.
What can I do to get my pcv and evap hooked up. I plan on just running my power brakes off the port in the manifold so thats taken care of. Is there anyway to install fittings into the carb? I'd atleast like to add one large one to T my PCV and evap into.
I know evap isnt necessary but what about the PCV?

no your brakes are never tied into anything else. one port for brakes, the other port for the pcv. No idea on the evap, i just delete it

Ok so run my brakes to the manifold then. But theres no other ports in the carb at all. None on the baseplate.
