inside

both black and tan are in stock....

What's the latest year you've seen a black cap on a dual point?

The problem I'm having is that while I've seen a few survivor 71 340 cars, all have been automatics (and had tan caps). I don't have any unmolested examples of 71 340 manual trans survivors to reference and have wondered if they are also tan (likely) but possibly black as well? Any input is appreciated.

I was just going through the parts books and it looks like the 2585000 cap first showed up in 1964 on the Hemi only. The other big blocks used a 1658534 for the dual point distributors.
They may be interchangeable, but they are two different caps and the neither superseded the other.
All the small blocks from the 66 273 up to the 71 340 that used dual point distributors, used the 2585000 caps.
The 1658534 is not listed as being used by any of the car engines past 65. This does not mean that the truck or industrial engines stopped using it past 65.
No mention of color.

my 71 4spd has a black cap but no idea if its original. spd 8/18/70 will have a look

NOW, is this written in stone? Absolutely not!!!!!

Did all 340's have dual point distributors as standard equipment?

Manual trans cars had cast iron dual point prestolites, auto cars had single point aluminum distribitors

'70 T/A & AAR had dual point, manual & auto. Kev

Sorru, I was only talking about 71 340's
