Date correct alternator for 12C '68 L34

[My68SS]

Hi all, would a 37A 1100794 alternator date stamped 7L30 be about date correct for a 12c '68 L34 w/o ac with an engine cast of 7K30 and engine build of 1204?

[KurtS]

Yes, that date looks good.

Thanks Kurt,
It's a re-buildable oneone I picked up of ebay to replace my obviously wrong one [date code, type, current, 2 groove L6 pulley - all incorrect] that came with the car.

Actually, after reading this current carby thread http://www.camaros.org/forum/index.php?topic=7068.0 in the decoding board, I realised I wasn't calculating the dates quite correctly anyway.
I was assuming an alternator date that had to be slightly before the engine date.
This assumption was incorrect as the engine date is for only the bare long motor [minus carby, alt, dist etc.]
Whilst 7L30 is valid, it could have been anything up to about 7M8 or even later - i.e. after the engine date would also be valid [maybe more valid?]

In fact, depending on the exact time line between fisher body building, engine final assembly and chevrolet vehicle assembly, an alternator date that is in the same week as the fisher body date may also be possible.....

[KurtS]

Yup, that's true.
Except dist came with the engine...

[My68SS]

Except dist came with the engine...

Opps, my bad. I guess that was fitted to block off the hole and prevent debris intrusion into the crank case?
Any idea what the typical time gap was between fisher tag build date and chevrolet commencement of assembly?

My68SS. That incorrect alternator you're replacing, would it happen to be an 1100813 dated no later than the first week of April 1968? Thanks, Joe.

Unfortunately not, it's a 32A 1100720 8E21

The Fisher tag build date only indicated the WEEK the body started in the Body Shop, not the DAY; could have been any day of that week. It took a couple of days to go through the Fisher system before the body went to the Chevrolet side of the plant.

[My68SS]

Hi John, sorry, didn't word my question very well - yes, am aware it indicates week.
But your quote of 2 days for fisher is about what I was looking for.
The other bit is the time from fisher finish to chevrolet commence? - would it be same day for bodies that are out of fisher early enough during a day?

[KurtS]

Rob,
The timing is spelled out here: http://www.camaros.org/assemblyprocess.shtml

Cheers Kurt,
Had read that report, though missed the bit in 'overview' where it quotes 2 days for fisher and 1.5 days for chevrolet [approx], with the entire process being virtually a non-stop line between the two plants.

It's a fascinating read, amazingly detailed! Thanks to John for compiling it!!
