Good job Held!
I wonder if the 1253 should be I253? But that would be a stretch for the date codes for each head. Jan to Oct? johnta1 Pontiac Power RULES !!! www.wallaceracing.com http://wallaceracing.com/johnta1plate.jpg |
held for ramsom thanks for the great info I'll double that head and the cowl tag #'s maybe I miss read the rear # if cmg is firebird 73 then maybe that 0662 is realy 0663 I'll have to doudle check after this latest snow 6-12 inch.Any luk on that ditrib #1112191?

1112191 is the distributor for the ZZ engine and XE engine (found in G-, A- (excluding station wagons) and F-body 455/automatic). It too should have a date code next to the number like 3A20 (last digit of the year, letter designation for the month and two digits for the day).
I believe the CM code was used for many years of the F-body cars. Mistakes I typed above... carburetor number should say 7043265 N(plant manufacture) should say N(plant manufacturer, Norwood, OH) [This message was edited by Held for Ransom on April 06, 2003 at 11:58 PM.] |

UPDATE:
after examining my TA's rearend I've come to realize that the second set of numbers (CM G 066 2 G) is maybe a shift designation. Dating rearend can be done by looking where I've pictured below. |
Held for ramsom thanks for the rear update,date code.I will get the other numbers when the snow melts.

held for ramson rear date is C23.Numbers on rim are M5 3 HM.Alternator 1100927 37amp 3C19 is 1973 March 19th? Full tag info
ST 732FS87N092788 TRA236 A51 75 75 03D WS4 050187 I double check the right head it is I253,is this date to far out to match.This seems to be the only number on the car that does not date match?What do you think? |

Did your rearend casting have another digit?
The date coding of the rim is shown below, looking on both sides of valve stem for numbers...2(Feb) 26. You have dated your alternator correctly. The 'A' in TRA (second line of trim tag) is throwing me as I've never seen it. The head number is off, but the car might have had a problem early on and was fixed by a dealership. All other numbers seem to indicate a numbers matching TA. |
I'll take a pic and post it.
