Distributor part number

[junkpile]

looking for a distributor for 440 with electronic ignition (orange box).
Must have the adjustable vacuum advance.

I have gotten 2 from auto parts store, neither one have the adjustable advance. I need that adjustability to fine tune the ping out of my motor, if I change the base timing I have WOT issues. I have never gotten a distributor before that did not have and adjustable advance, part stores are not carrying the good stuff anymore it seems.

Oh, one thing I've discovered with some of these aftermarket units...they say adjust with a 3/32" allen, but that doesn't always fit the screw inside it's actually a small metric (sorry don't remember the exact size..)

Thanks for the advise. I purchased a Proform Distributor, said it has the adjustable advance from summit. This should solve my issue.

advance auto could not verify the adjustable advance and they have nothing on the in store computer that gives any information on it. If it is adjustable they need to have it written somewhere especially since its a pre paid order.

thanks for the information, it was a great help and got me to the right place
