'95 ZR-1 battery is judging guide correct ??

[Bob B.]

I own '95 ZR-1 serial #00003 box 47 on build sheet "battery" is marked 484 am I correct that calls out a 484 Delco Freedom battery was installed originally ? The 94-96 1st edition judging guide page 160 says 95 ZR-1 should have a Delco Freedom 674 battery Anybody out there with a 95 ZR-1 what battery is on your build sheet ? or original car ?
What are the chances of finding a 484 Delco Freedom battery for show ? Been watching Ebay for months
I hear that a proper size, shape ,color current side post Delco with the proper repro sticker still only scores 50% originality- ie 10 point deduct- going by configuration, date,installation etc that 50% / 10 point deduct seems pretty harsh.

Bob,

AFAIK the ZR-1 battery was a AC-Delco 75Z-72 what ever Delco battery number that equates to.

IIRC the ZR-1 labels are unique.

Have you tried searching the ZR-1 Forum?

As Gary noted, all 1994-96 batteries are series 75. Note year changes in battery "CAT NO." labels on pages 158-161 all those examples show "6XX" CAT Numbers. You might contact National Team Leader Tom Barr to see if he has seen any "484" examples.

Batteries are judged using Standard Deduction Guideline #2 with 50% deduction for correctly sized service replacement Delco with correct posts. Batteries are not judged via C.D.C.I.F. criteria.

Bob,

BTW, do you have the foam a.i.r. pump filter on your ZR-1?

Dave Houlihan can tell you how I learned about that foam filter on the a.i.r. pump.

Your build sheet will indicate under "battery" what battery number was the original one.

Here is a picture of an original ZR1 battery. I believe it's for a 95. But check your build sheet, that's the sure way to tell, regardless what the judging manual indicates.

The 1995 ZR1 had a Battery that was Cat 484 until December 1994. The last ZR1 with this Battery Cat Number was 800293 and had a white casing. Cat Number 674 was started with the next VIN of 800294 and had a black casing.
I located a number of these batteries and have photos of the date codes and sizes if anyone is interested. They are not for sale as I have tried to purchase one.

I cannot imagine that even a single example of one of these batteries would be functionally usable. So, I can understand how they might be of historical interest but I don't understand how they could be a part of a meaningful restoration for anything other than a non-operational, display vehicle (e.g museum display).

Joe, The case could be "cored" and an small AGM battery installed. I have seen this before. The "eye" is the hardest part to replicate but it is doable.

What is the CCA rating of the battery installed in the case?

Re: '95 ZR-1 battery is judging guide correct ??

Folks, the 1994-96 NCRS Judging Manual on page 159 incorrectly displays a battery with a Cat number of 693 as the correct battery for a 1994 LT1.
This is incorrect as it should be a battery for an LT1 should be cat number of 655. No cat number is given for the 1994 ZR1, it should be 484.
On page 160 the information on an LT1 is incorrect. It states the 1995 battery had a cat number of 655, this is partially correct in that in December 1994 this was changed to a 671 battery. Also incorrect is the statement that the 1995 ZR1's had a cat number of 674, again this is partially correct in that a battery with cat number 484 was utilized until December 1994 and then changed to a battery with cat number 674 .
On page 161 the information for the LT1 and LT4 battery is also incorrect, the cat number shown is 655 and it should be 671.
This information has been passed on and discussed with the National Judging Team Leader and the appropriate changes will be incorporated in the revised 1994-96 Judging Manual

Re: '95 ZR-1 battery is judging guide correct ??

I have no idea. Not my battery. But, I imagine that setup would be for display only and driving short distance, due to possible heat buildup inside the case. But at the end of the day, something like that (if done correctly) can save you ten points.

Just as long it doesn't do this.....

But whoever did this one used speaker wire. Bad.

PS I fear there are more conversions out there like this.

Re: '95 ZR-1 battery is judging guide correct ??

The ones I have seen cost the buyer >$2000 not sure they get what they pay for, but I assume the biggest use they would get is an OPs check. They used some pretty heavy wire (6g +) to connect to the existing lugs. Eric
