gotdust · 07-19-2008, 11:58 AM

i want to add some timing to my 73 360 duster with electric choke if it matters, how do i set it with vacuum advance, and what do i need to do it that way or can i just plug off vacuum at dist and do it there? i want about 38*. thanks

You should be able to do that through the vac hose hookup with an allen wrench. I have never done it .. but will be doing it for the first time on an RV project I have.

is there a allen head screw inside of the hose port on the vac adv module?

There SHOULD be ..... at least on the ones that MP sells.

i think the allen screw was used on stock 318's in 68 or 69. you might find an aftermarket unit that will do this.

I think that ALL kits and separate distributors that MP sells has that feature. And this even includes the /6 !!

I have never seen a "chart" .... just do it by trial-and-error.

you could use a timing light to measure the before and after results.

OR ...take to to someone with a distributor machine.
