1969 350/350 Distributor Questions

[Steve M.]

Doing a frame off on 1969 350/350 convertible and started on going through the distributor. The points and condenser are a replacement set. Picked up a set of Delco Remy 1852130 D1001 that are 'supposed' to be correct. If not correct, can anyone provide the correct parts number? The Vacuum Advance is MS 360 12. Is this correct? If not, what should it be? Can a Vacuum Advance be refurbished?
Any help appreciated.

Original points were GM #1931988. Original vacuum control for your distributor was GM #1115360. I don't know of any reliable way to rebuild a vacuum control. I'd be suspicious that any rebuilt vacuum control would meet specifications.

You might find this article useful http://www.lbfun.com/warehouse/tech_...ance_Specs.pdf. If you google Lars Grimsrud you will find many useful articles by this man.

Currently available "brand name" point sets including Delco are all manufactured by Standard Motor Products, and there are several different point sets depending on the application. I authored an article in The Corvette Restorer a few years ago on the differences and recommended sets for varrious engine configurations. The text is also in the TDB archives. Judges will typically ask you to open the window so they can see whether the distributor has points or an electronic switch. I, at least, don't attempt to judge whether the points are the "correct" original part number, but just look so see that points are installed.

The VAC is worth three points, two for originality and one for condition. As long as there is no visible rust, they are okay by me, even though the plating may be faded. If the VAC is functional (0 @ 6" 12 @ 12") don't replace it. There was also an individual who reported in detail here on the TDB about using one of those home plating kits to replate a VAC, so that's an option, but before you try that just dress it lightly with Scotchbrite to remove any of the typical white oxidation, which should give it a more uniform patina.

Using DR points and condenser is very iffy. John

I have found that your GM #1852130 are OK. What it amounts to is that GM #1852130 is NOT a points set. Rather, it is a UNIT which consists of a GM #1931988 point set + GM #1932004 condenser.

By the way, I much prefer the uniset which consists of an integral point set and matched condenser. It was not originally used for 1969 but can be used for any 1962-74 single point distributor.

IIRC the Uniset will not fit under the RFI (Radio Frequency Interference) shield used in later 1970 and newer Corvette distributors. Most cars really don't need the RFI shield, but if NCRS or NCCB judging is within your sights be aware the judges will look for the RFI shield through the distributor points adjusting window.

You're correct; a Uniset will not fit under the RFI shield. However, this is a 1969 distributor and no internal RFI shield was ever originally used for 1969.

Right you are Joe. I need to pay more attention to the title.

Joe,

Upon further reflection I am thinking that I didn't see any sales literature for the Uniset until late in 1970, perhaps into the 1971 model year. Was the Uniset available at all in 1969?

I am pretty sure the Uniset was not factory installed through 1972 PRODUCTION. Was it ever a PRODUCTION part for any Chevrolet model?

Re: 1969 350/350 Distributor Questions

Uniset not really for high performance engines such as your 350 hp. Read Duke's article and get one of the sets he recommends. I had the point spring on a uniset break on a '66 L79 I once owned.

The Uniset was never used for any PRODUCTION Corvette distributor. In fact, the Uniset was never even cataloged in SERVICE by GM for a Corvette distributor although it was so-cataloged by Delco.

Why do I like Unisets? Is it just ease of installation? Absolutely not. In a Uniset the condensor is matched to the point set. In this manner, the transfer of metal from one contact to the other or the general erosion of contacts is minimized. Unisets work very well for most Corvette applications.
