I read somewhere, perhaps here on Moparts, that the earlier years used the stamped blades and later used ink.
Not sure if by later meant 70-71 up ?.
Perhaps it had to do with AC as well.
The majority of AC cars I have seen had the stamped numbers.
Could also have been more than one vendor for the blades, one stamping them, one using ink.

And I heard the same but based on Barry's 70 examples (stamped in metal) vs. my ink stamped examples, I'm not sure which happened when or why. As you mentioned, a second vendor could easily be the case.

If any of you guys have any 216 or 215 blades (stamped either way) and know what year car etc. they came off of, please post your examples.

71 cuda 340 4speed no A/C 923 SPD stamped in metal blades

Thanks Wizzard, perfect example!

This is a 215 fan from my 69 340 4-speed with factory air. 69 340s with no air had the same 215 fan. But only 340s with air did have this thermal fan clutch part 2863263 (except clutch 2863266 if 2.76 axle). Non air 340s had a different non-thermal fan clutch. The only marking I found anywhere on the fan assembly is this 46237 emboss on the hub.

This fan clutch is a parts counter replacement date coded 7/30/73 (G30=7/30, year=DB?) but otherwise identical to a 69 factory Eaton part, according to Pampered Corvettes, who recently restored it with a date code preceding my SPD 11/8/68.

VIN# 1B212538 approx. SPD 11/15/70

block casting date 7/2/70

Doing resto on 1972 Duster 340 4 speed car. Hundreds of photo's of several
original cars including my buddy Dave's black low mile Duster

Now just need to figure out how to post some pics. Been reading post on here forever and also recovering from cancer so my car's resto as slowed down for now but still read a lot of posts. this is a subject I can contribute too.

Welcome to the party Scott Harms!

Dmoore, not sure I follow you? I started this thread quite some time ago

Va58, working on a 72 Demon 340 4 spd. Would love to see some of your original pictures.

72 Duster340,auto,3.23 SPD of 419, non-ac car, 36,000 miles...





And fan clutch...#2863233 6"

Interesting, your 72's fan blades have stamped numbers (not ink stamped). My 71's was ink stamped. Since I've seen both versions on multiple years it points towards more than more than one supplier.
