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.

IMHO this #2 post is the correct answer. Post 12 backs it up Stuff I posted is referencing a 69. To finish the 69 story this is the cap that was on the dist pictured above. No "R" as you can see. The thread I linked started as a question about the originality of some parts that were removed to get car running after its long nap. As you can see the cap was dismissed as replaced. I bought the "R" one as it was supposed to be"correct". Then conflicting info shows up later. The no "R" cap is on car but we have the 'R" one [minus overspray" on the shelf. Always looking for more clarity on stuff including this. Pic 1 is the "R" cap we bought for it. Pic 2 is the no "R" cap that was on dist. Pic 3 is the coil that came with car Pic 4 is date and purple ID paint on dist that came with car. |

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. |

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 Ive asked Charley Lillard to get a picture of the assy line cap on his former LOW milage 70 Z............

"Patent Pending" cap is for 1968 and earlier for all GM models.
