which vacuum port
'86 351W w/Edelbrock 2181 intake, Edelbrock 1406 carb.,no emissions or related hardware, no A/C or related hardware, Hedman Hedders, MSD 6 series ignition, 2 1/2" dual exhaust. (Originally set up for emissions control.)
Anybody know if the distributor vacuum tube is supposed to go to the emission or non=emission side of the Edelbrock 1406 carb. if the engine has no emissions? Only sign of emissions are blocked-off exhaust outlets on back side of heads.
I assume it can be tuned for either?, but don't really want to screw around with it that much if I don't have to.
Thanx for the advice...

If both ports didn't have vacuum on acceleration I wouldn't be asking about it.
There's no need for a lot of things people do! Especially ones suffering from sporadic bouts of immaturity, such as myself.

Well from the factory it was set up with timed vacuum (facing carb left port) starting with 6-10 degrees initial.
You may wanna explore full vacuum (facing the carb right port), I have done some reading and since tried it, the engine performs like night and day, in a positive way. I don't plan on changing it back to timed any time soon. later

Sorry about the poll and the... immaturity.
Thanks for the input, I currently have it on the right-facing port because of the difference in performance. Didn't know if it was pure chance in adjustments or if that was the correct side (kind of figuring things out as I go). Thought it was possible that I had things so screwed up that the wrong side worked better.
