vacuum advance? again ?????

[darmentle]

I just noticed that the previous owner never hooked it up where is a good place to plug it into on the carb i have a holley truck avenger. i haven't had any performance issue with disconnected.

Part2
So i connected the vacuum advance and now when i drive between 1500-2000RPM i hear a strange KEk kek kek sound coming from what i think is the distributor. it only does it under load and  goes away a little after 2000Rpm. Thoughts ?

sorry if its a wrong link, cant open it on my school laptop. there should be an open port somewhere to connect it too.

Thanks i see the little male fitting on the carb that says Timed Spark Vacuum Source Do i have to Check the timing after i hook that up .

No, you should always set ignition timing with the vacuum advance disconnected, then re-connect it.

oh i was gonna ask since we are talking distributors is there a difference in a normal HEI and MSD HEI i got the 6al box and wires just haven't got around to installing it . I was debating on getting the MSD  distributor is it worth the money
