440 distributor

I just purchased a distributor on ebay item #230422363671 for my 70 Dodge challenger 440 4 barrel 4spd. After getting it I realized it might be incorrect. The red anodized tag reads the 3438222 which is correct but the date is 6 9 which in my mind is for a 69 build and the vacuum advance part # is 2642262. Does anyone know if this is correct or can I use the distributor and change the advance and put a repro date correct tag on it? I would even consider purchasing a correct one if there is one available.

IIRC, a 440 4-speed in '70 should have had the Prestolite dual-point distributor. That's a Prestolite vacuum advance pod, but the distributor itself is a Chrysler version. After reading his ad and him claiming it's even for a v-code, that's absolutely wrong. Again, the iron Prestolite dual-point is for a '70 v-code and 4-speed u-code. The automatic u-codes would come with the Chrysler single-point and the v-code autos, again, would come with the Prestolite.

Maybe I'm wrong, but I know for a fact a 440 4speed car in '69 would have the dual point.

Based on the info I have in my books all 440 4 barrels will have a single point distributor regardless of the tranny type. He had told me the vacuum advance changed mid year and went to an electronic one. Do not know if this is correct.

1969,
440 auto, single point
440 4spd dual point
69 1/2 both dual point

1970,
440 4spd single point
440 auto single point
440 6pk dual both.

6/9 date code is June,a little early but possible.


These are both are 70 6pk,early on right,late on left.

Also,Troy if that is a picture of a 69 engine,it has the wrong vacuum advance.

That should be a '70-1 440 since it has the 1/2" and 5/8" heater hose fittings. '69 would be 5/8"- 5/8"
