Hi All, I have a delco remy tach drive dist here with a red band that reads 1112021 DELCO REMY 2H 2

Can anybody tell me what these numbers mean?
Thanks!

1112021 is late production 1970 for a 350/350. 2H 2 I believe is dating. I'm having a senior moment, but I think it works out as follows: "2" second day of the month, "H" August, "2" second shift.

Thank you very much!

Can anybody please explain what the raised casting numbers at the top of the casings represent?
I have two different units.
One says 190 and the other says 691

Thanks.

Bob,

I believe you have a replacement distributor. The distributor is for a 1970 350/350, but the id band says 2 August, 1972. It's yr/mo/day. Of course, you could have the wrong id band, they're easy to remove and replace.

The casting number on distributors has never been a source of any meaningful info. Still a mystery.

Hmm.... Now I'm a little more confused.
Thanks very much (I think)

Anybody else want to confirm?

Thanks guys!

Chris, would a "replacement" unit still be considered "correct" to a person that is looking for a proper year distributor?

Heres the issue I'm having.
I bought a spare tach drive dist for my '73.
I bought it from a local guy that was parting out a '70 350/350.
I sent the dist to Lars and he rebuilt it completely.
New shaft, bushings, drive gear, coupling, vacuum control, ect: then Lars also set the advance curve on his SUN machine.
I installed it on my beefed up L-48, it worked flawlessly.
Shortly after this I bought a ZZ-4 and went with an HEI tach drive.

Bottom line is that I have a lot of money into this distributor and I want to sell it but I don't want to advertise it as a 1970 unless I'm positive that it is indeed from a 1970.

Can anybody tell me if there is an accurate procedure to verify the year of this distributor?
I have attached a couple of pictures so you can see the unit and the numbers.

Thanks for your help so far guys. I appreciate it.
Bob.

Bob,

There are some numbers under your cam and weight plate (under the plate that holds your springs and weights). Should be CCW xxx . Plates have different slot lengths that allow different amounts of centrifigal advance. Some people have a cross reference to actual part numbers that can help narrow down the application.

The other way is to look at the part number on the vacuum can, but I bet Lars swapped that out. Did he set it up for your L48? If so, it won't be right for a 70 350/350, different specs.

Chris, Lars did change out the can, he uses one type and one type only (B28?) or something like that.
I have no idea how he set the curve, he did it on his SUN machine.
The L-48 was probably close to 280 hp gross.
I didn't consider that aspect of the setup but I guess that it would matter seeing that one engine will wind up quicker than another depending on the power.

Oh well, maybe I'll just sell it as a completely rebuilt unit that may or may not need to be re-curved depending upon the application.

Thanks Chris!
