Dist Cap ID ????
 

What is correct DELCO Distrib Cap for 1970 Z28 ???

I have this with Delco - Remy R & PATENT 2769047

AND I also have a similar Black Cap with NO LETTERS/NUMBERS

The 1970 Z/28 would have had the "Delco Remy" "Patent Pending" R distributor cap from the factory. The "Patent" 2769047 and the cap without letters would be a service replacement cap.

mhm1966, So my above pictured cap is NOT Assy Line Correct !!!!!!!!!!!

and there was Two different service replacement caps ?? One like above
and 2nd .........without any writing ???????

Chuck, the cap you have in the picture is not assembly line correct for a 1970 Z/28. The cap is a later style replacement cap that was used in 1973 production. They made several different versions of this cap. The one you have 2769047 with aluminum contacts, 2769047 R both with aluminum and copper contacts, and some had other letters like T and BH on top of the cap.

early and late "patent pending" caps.
Pic 1 is earlier type. No "R"
Pic 2 is later type with "R".
They are saying you need bottom type.

MHM1966, Thank You for your replies...........

Interested to learn what/where is your source of info so as the Camaro Nat'l Judges
will "Believe"

What 1970 GM V-8 engines during what months received which cap ???

and 1971 etc etc...........

Did the " PATENT 2769047 R " not start until 1973 ??? and all 70-72 received
the PATENT PENDING.......

Thanks for your patience, if you have any left
