venting gas tank vapors

My 1979 Impala has a new stock 350 SB crate engine (no performance add-ons, no headers, no emissions control). The new intake manifold and 600 cfm carb  are Edelbrock. The tranny is automatic. I wish to vent the gas tank vapors to the correct place. I don't want to affect engine performance nor do I want to smell gas after the car is parked in the garage. So, what connections should I make in the engine bay to the hose which runs from the gas tank. Right now it's connected to a charcoal canister filter. If that's ok, where should I vent vapors from the canister? That's my question. For those of you who have an engine set up similar to mine, what do you do with your vapors. Maybe the answer is obvious. If so, I'm sorry but I'm not sure what it is. In my State, I'm exempt from emissions testing. Thanks for reading my post.

lol I had just posted a thread similar to this in another forum I am not as lucky as you though, and my charcoal canister is gone. Anyways, since you do have the charcoal canister, a hose runs from the fuel sender in the gas tank, to the canister, and from the canister, it goes to the carb.

What he said ↑↑

So, I'm going to send the vapors from the charcoal canister to the unused non-ported vac inlet on my 600 cfm Edelbrock carb and not worry about any effect on engine starting or performance? Thanks to both of you for the replies.

That doesn't sound right to me it should go to the ported vacuum on some it is bowl vent

but on the edelbrock just hook it to the left side of the front of the carb. Your distributor goes

to the right the manifold vacuum. Ported vacuum for distributors was a cheap emissions trick

of Car companies in the 70s before computers it lowers emissions at idle but does nothing

for mpg or hp.

Thank you Myloth. I will try your suggestion. The reason the distrib vac, at this time, is taken from the ported side of the carb is because an Edelbrock YouTube video directed me to do so. No matter. One last dumb question on this subject. Does moving the distrib vac from ported to non-ported affect the timing? I'm guessing no.

Yes it does at idle it increases the timing as long as you are at or near factory specs on timing

 it smooths the idle out, it may increase your idle speed just lower it and you should get better

mpg and throttle response. And as I said before the only benefit to having it the other way

around is lower emissions at idle nothing else.

Many think it's proper to use the ported for the distributor advance but that

is because the cars came that way from the factory and it was all just an emissions thing.

There are several good articles about this one was in Hot Rod I think it's online.
