69 dated alternator

Re: 69 dated alternator

Well it looks like I may have multiple expensive, impossible to find, alternatives including: 1100833, 1100881, 1100900, and 1100825.

Here a post from corvette forum from data in Rick Bizzico's book:
Here are the '69 alternators, per the 1969 Stingray Guide Book, Rick Bizzoco.

Option Base C60/K66
ZQ4 Base eng. 1100859 1100884
L46 1100859 1100884
L36 1100883 1100825
L71 1100882
L88 1100882
The C60 and K66 requird a stronger charging system. The K66 option (transistor ign.) option utilizd 6.25 amps to run the system compared to 2 amps for the conventional distributor. This increased amperage need was met with a 61 amp alternator.

The 1100825 or 1100882 would not have been used for your application. That's a good thing because those are the most difficult of ALL alternators to locate. 1969's have been stolen just to get one of these.

I still think the most common alternator for your application would be the 1100833. However, it could also have been the 1100881. I highly doubt the 1100900 but it is a remote possibility. The fact of the matter is that the ONLY way to KNOW what alternator was originally installed on your car is to have that original alternator. Since you don't have it, you can NEVER know what was originally installed. So, look for any of these. If you find an un-restamped example that is within 6 months of the build date of your car, it will be considered NCRS correct and should receive full points on originality. If you find one that's within about a month of your car's build date, that very alternator could have been originally installed on your car.

Are these scratches accross the numbers and date codes fixable?[ATTACH=CONFIG]53404[/ATTACH]

I would not even attempt to remove these scratches. Any effort to remove them is going to create questions regarding the legitimacy of the stamping and I do think this is an original stamping. I'd have the alternator restored WITH the scratches and suffer any minor condition deduction.

Re: 69 dated alternator

Hi Joe...Thank you for your expertise and clarification. I do have 1970 454 heads on my 1969 427, so maybe there's a chance that 1970 900 alt would apply. And my intake manifold is dated 1 day prior to my ship date, so there must have been fast paced production runs in November of '69...Don

Don, what are the casting numbers and dates on your heads (and the date on your trim tag)? 1970 454/390 heads used the same casting number as the late 1969 427/390 heads (3964290).

The intake you have, if dated 1 day prior to your car's ship date, isn't original. The intake was installed at the Tonawanda engine plant when the engine was built so it has to be at least several days prior to your cars built date due to logistics. It took several days from initial casting, to assembly to shipping to St Louis for installation.

Re: 69 dated alternator

Opps, my intake casting is good as Sept 16th; I guess I wasn't thinking correctly when I woke up at 3 am

Right side head GM8T; J 25 9 (= Oct 25, 1969); 3964290; PASS

Left side head 3964290; GM10T; J 23 9 (= Oct 23, 1969); PASS

Intake Manifold Casting with bottom shield off: 9-16-69; 5469; 2947801; 7/25/08

I'd say it's original and quite a rare alternator at that. If you could post photos of the front and rear of the alternator I might be able to give you additional confirmation.

Re: 69 dated alternator

I have been to John Pirkle's place in Augusta, Georgia. He has I don't know how many alternators, starters, etc. A call would be worthwhile.
