help with holley 2 bbl vacuum hoses

What does #5 do

Supplies manifold vacuum for things like EGR (if you're running it, sounds like you're not) and heat/AC (hose from "#5" fitting to the vacuum reservoir).

No emissions

Meaning...what-all, exactly? Sounds like you removed some stuff (charcoal can, for example) that only works for you, not against you. The charcoal can traps gasoline that would otherwise be lost out to the air, and stores it so you can actually use what you paid for.

I am prolly going to leave off the PCV valve because I am running M/T valve covers and the hole is too big for a grommet. Is this ok

No, it is not OK. It'll crap up your oil (and the inside of your engine) with dirt and water much faster than if you have proper crankcase ventilation installed. And you'll get a pukeworthy odour of crankcase fumes inside the car. PCV is another system that works for you and not against you. Don't just yank and throw stuff away because it's "emissions" equipment.

The M/T valve covers have only big grommet holes? Fine, there's an easy way around that. Get a Stant 10078, Wix 42997, or AC-Delco 12C26 breather:



Get a grommet, Dorman #42344 (breather grommet for 1970-1995 Chrysler products), install the grommet into one of the valve covers, and push the breather into the grommet. This breather has an internal filter and a 1" top hole, so just snap a standard Chrysler PCV valve grommet (such as Dorman # 42064) into the top hole and pop a standard Chrysler PCV valve into the grommet, and you're all set. The other valve cover gets a vented breather cap and serves as the crankcase inlet air cleaner.
