Old26Buick 14 Posted November 28, 2009 Share Posted November 28, 2009 I bought a Delco 640K 46991 Distributor for my 27 but doesn't fit. Does anyone know what this would fit?? Thanks Link to post Share on other sites
Buicksplus 4 Posted November 29, 2009 Share Posted November 29, 2009 I have a unit off a 28 and it is designated a 640Y. This unit should fit to your 27 generator. This distributer uses the cheaper Chevrolet points and the timing is adjusted by rotating the distributor -- rather than via the drive gear on the 27.I use a distributor like this on my 27, it fits and works great.

straight8pontiac 7 Posted November 29, 2009 Share Posted November 29, 2009 Old26BuickUsing a Hollander Manual as my reference, I have found that a Delco 640K was used on a 1929 Oakland All American 6. No other reference is made for the use of that distributor on any other vehicle.The 640Y which Buicksplus mentions in the previous post is referenced for '30 Buick and '30-31 Yellow Cab Taxi 6.Dave Link to post Share on other sites
