Saw the thread a week or so ago about NAPA discontinuing this vacuum advance can, and based on the posts by Clem and Duke, I decided to pick some up locally in Tucson. I got 2 from Phoenix, cost was about $10 and change each. The counterman said the part is not discontinued, but has been relegated to factory stock only, vs store stock. So, I guess they will continue to supply the part by special order....Craig

Re: NAPA/Ecklin VC 1810
You guys have been depleting all the store stock. The inventory analysis guys are probably wondering why there's a run on these parts.

True! But I like the parts in hand...controls your destiny just in case. Is the VC1818 similar to a Delco 236? Thx!...CraigComment

Re: NAPA/Ecklin VC 1810
Yes, the VC1810 is a direct replacment for the Delco 236, and they are the same within the limits of manufacturing accuracy. In fact, if you buy a Delco 236 I believe you now get the same Dana Controls part as identified by the "B28" code on the mounting bracket. It's my understanding that GM just buys them from Dana and puts them in a Delco box.

Duke - thx, I have a NOS Delco unit from Dave Fiedler, still the Delco brand with the old style with 236 and degrees of advance. I got this one for my 67 L79 for judging....but it was $75 not $10....CraigComment

Now I know why my guy says he has to special order them from the States.Comment

Re: NAPA/Ecklin VC 1810
Yep...but at least they sound like it will remain available....for now...however, if all us NCRS types cause a run as Duke mentions, maybe they will return as a store stock part!....CraigComment

Re: NAPA/Ecklin VC 1810
And Duke thought nobody was listening... We are paying attention now.

Re: NAPA/Ecklin VC 1810
Sometimes I wonder. I think I've written the equivalent of a novel over the past couple of years on the subject of matching the vacuum can to the engine's idle vacuum characteristics and the roll the vacuum advance - namely an usuitable vacuum map - can play in overheating.
I rarely criticize Chevrolet Engineering or recommend modifications, but the vacuum can is something that they didn't always get right in the pre-emission era, and , of course, for the emission era, the ignition advance map was based on meeting the emission bogeys, not engine efficiency.
For SBs the ideal setup was achieved in '65 for both medium performance (250 and 300 HP engines) and SHP/FI engines. For BBs they never did get it right IMO.
