1969 427/390 alternator ID

[Joe T.]

I have an alternator that I think belongs to this car. The casting/part mumber on the case is 1100882. Other stampings are 61A (rating) and 9E9 and 2VNIG. As always, any help is deeply appreciated. Thanks and regards...joe

The 1100882 came on the 435 and 430 horsepower 427 in 1969. Should be an open face front with an additional heatsink on the rear case. Your date code is for May 9 1969 and I believe you are looking at "12V NEG" in the stamping. Your car would have come with a 61-amp alternator if it had A/C or Transistorized Ignition. Scan down and join the thread "69/70 Alternators 1100884 vs 1100825".

Hi Mike:
Thank you very much for the info. I read that thread before and I didn't see what I needed (the "882" discussion came a bit further down). Honestly, when I read it, I didn't even have the alternator in front of me (missplaced!) I will join that thread if I have anything to contribute like: How did the 882 get into an L36? I have the A/C but not the K66 T/I. Thanks again and deepest regards...joe

Re: 1969 427/390 alternator ID

This is my understanding of 1969 alternator numbers.

Alternator .. Amp Rating .. Application

1100859 ...... 42 ............. 300 and 350 horsepower base unit

1100833 ...... 42 ............. 390 and 400 horsepower base unit

1100825 ...... 61 ............. All with air conditioning or transistor ignition

1100884 ...... 61 ............. 300 horsepower with air conditioning

1100882 ...... 61 ............. L71, L88 and L89 with K66 transistor ignition

Re: 1969 427/390 alternator ID

Thanks Mike: I got information similar to yours from the 1970 (69 vette) chevrolet service manual, but it had a lot less detail than this. The manual has some of what you have , but it doesn't differeniate from some of the high performance options in this (alternator) area. This car is somewhat of an enigma to me, since it seems to be composed of some disparate parts, like this alternator. You guys are a WEALTH of information to me and I appreicate all of it. I hope I can contribute some myself. I am going to post some of this in the earlier thread and see what comes of it: The 882 alternator in an L36?. Thanks again for oyur help and interest...regards...joe

There is absolutely no reason that the '882' alternator could not have been used interchangeably with other 1969 61 amp alternators. It's identical in every way. Based upon your number and date, I'd say it's original to the car (assuming that the case configuration is correct).

Re: 1969 427/390 alternator ID

Thanks Joe. It looks like the case is correct in the ways described, down to the "no rectangle" under the "DELCO-REMY" on the back of the case. Is there something else I should look for? The case does not look like it was ever disassembled. By the way, the VIN for this car calculates out to a mid-August build date according the the C3 registry.

You guys are THE source of information on any questions I could imagine. I was amazingly lucky to find this link and more to the point, get your help.

Hi Mike: You were correct about the "12V NEG" on the case. It came up with a little striking woth a pencil lead for readibility...RThanks again...Regards...joe
