You should add that these are 70 71 hp manifolds.

Yes they are. Here is the date coding for left and right. They come from a b and c body car.
440 1970-71 B - C Body / Right 2899879
440 1970-71 B - C Body / Left 2951865
 
OK, here are the dates and date code.
440 1970-71 B - C Body / Right 2899879 -- 68 7 or upside down 189, most likely 189 — what date corresponds?
440 1970-71 B - C Body / Left 2951865 -- 8/19/70

What happened to the rest of this thread????
There were 2 pages now there is only one.
I want to see the full list please.
 
I don't think there was another page on this thread. There is another set of manifolds on another thread that I noticed was missing the first page. Let me see if I can help, what is it you need to know?
 
thank you
Somebody listed a full listing of manifolds and the part #'s and years they fit.
I have a set or two that I want to sell.
It's best to know what they fit before listing.
 
I think that one date code is 1-8-9 it's actually upside down. You can tell by the 8
 
Well, I thought that might be the case, but why would one manifold be upside and the other date code upside down. Seeing so many imperfect stampings, I thought that the “68” looked more familiar and made more sense than “89”. So, given we are on the same page, what does the date code 189 correspond to? When was it cast? That “1” looks curvy like a “7” would be, but I still agree with the way the “8” is an upside down “snowman”.
 
I'm no expert but would think either January 8th of 69 or even like you said, maybe it's a 7? So July?
