Of the slightly more then 8200 tripower cars built in 1964 does anyone know about how many were automatics?

Very cool!

[Tom Vaught]

HAVE SEEN THE "NUMBER" POSTED SEVERAL TIMES BUT YOUR SHEET IS THE "REAL DEAL" THANKS FOR THE TRANS BREAKDOWN!

Not to many of those auto Tri-Powers for sure.

Is 7/01/64 the last date for the builds ?

No. Mine was built 7/24/64.

No, they were still casting '64 blocks in July and assembling engines in July also.

The latest block cast date I have logged is July 7 with an EUN of 600xxx. The highest EUN I have logged is several thousand above that and went into a Kansas City, Kansas built Bonneville with a Time Built code of 07D, unfortunately I was not able to record the cast date on the block.

I have never recorded an August '64 built Pontiac from any Plant, so I believe final production at all Plants may have stopped on or about Friday, July 31, 1964.

Chris has posted that engine log before, great info for reference.

But likely there was another 4 weeks of Engine Production and Car Assembly Production before they began the Changeover to '65 production.

They were building about 10,000 Pontiacs/week, combined total for all Assembly Plants with about 1/2 being built at the Pontiac home Plant. And all Engines were assembled in the Engine Plant at Pontiac.

I don't know what the Credits and Debits represent or how you could have a negative no. for production of the 84Z code engine assembly.

But I suspect you can roughly figure another 100 or so auto trans GTO Tripower engines produced in July, guessing about the same as for the prior month.

And if they were all installed in actual builds, you could figure roughly 800 '64 GTOs were built with the auto trans and Tripower.

However, if you add up all the GTO engines thru June, you get 30,187. The oft reported official total says they built 32,450 '64 GTOs. I don't know the source for that figure or how accurate it might be.

But that suggests they only needed 2,263 more engines in July. If only about 1.8% of the June GTO engines were 77J (95 of 5177 total), then perhaps they only assembled another 41 or so 77J engines in July for a Grand Total somewhere around 734 for the year.

Not sure where you got the 8245 Tripower figure, it is the same no. as Eric White showed in his book and as it happens, same total of Tripowers as reported on this Engine Production log.

I know the total no. of Tripowers assembled in July was NOT zero because as it happens, the engine assembly I mentioned above with EUN 600xxx was a 77J installed in a Pontiac Plant built GTO with a block cast date on July 7 and the car shows a Time Built code on the Data Plate of 07C.

So IMO, the 8245 figure is NOT correct. Most likely, an additional 500-1200 Tripower GTO engines were assembled in July after this Engine Production Report was produced.

Thanks for the New Info John. Will footnote the info I have copied as incomplete info for the whole production run.

I would add that my 64 GTO Tri-power 3-speed stick with a production date of July 27 has block casting date of July 8 and an EUN in the high 601K range. I believe it to be the original engine - but...

The PHS docs should have your cars EUN, at least mine does.

Perfect, thanks.

Unfortunately, mine does not (unless I finally need glasses). It was my understanding that the Pontiac built cars seldom show the EUN on the docs you get from PHS.

[rexus31]

As stated above, my '64 GTO was built 7/24/64. It was an original Tri-Power, 4 Speed car (76XW) with an EUN of 611673 per the PHS. I don't know what the casting date was as the original motor is long gone.

[rexus31]

My car was built at the Kansas City Plant.

'64 Pontiac Plant PHS docs NEVER show the EUN (even if you wish to avoid NEVER and ALWAYS, LOL!).

'64 Fremont PHS docs do show the EUN and almost always quite legible.

The '64 KC/Balt Chevy form PHS docs will have an imprint of the original Ident-O-Plate on them and the Ident-O-Plates included the Engine Code and EUN (for warranty control).

Most of the imprints are fairly legible but since it was an inked stamp on the original Passenger Car Shipping Order form and the records were later copied to microfiche and the copy you get from PHS is a copy from the microfiche, many times the EUN won't be very clear although if you know what it "should" be, it is often clear enough to confirm it.

1_Wild_Cat, the EUN and cast date sounds like they match to each other. Whether that block is original to your build can't be proven unless you have the original Ident-O-Plate. Normally, EUNs moved very quickly from the Engine Plant to the Final Line at the Pontiac Plant.

But your car was assembled during a period that I refer to as Model Year build out, a time when the Plant would be piecing cars together from available inventories. Whether an "old" Engine Assembly was likely to be made part of a build at the Pontiac Plant during that time I have no idea.

But unless other info is found, I have no reason to doubt that your engine is original to the car.

rexus31, too bad you don't have that block. I would be curious to know the block cast date.

I should have checked my pile of "yet to be logged" EUNs. When I was posting, I was sure I had a record of an EUN 610xxx. But it wasn't on my log.

Turns out I did have it in my pile but no cast date. It was matched to 824P297789, this was a July build at Pontiac but I don't have the exact date of production. If somebody knows the GTO or if 1_Wild_Cat can tell me how close to the end this VIN was in '64 compared to his, it would help pin it down.

But I also see that I have an even later EUN in my pile. A G104 (July 10, '64) cast block made part of a 76XW with EUN 613043. The GTO was not with it but this one qualifies as the highest EUN and latest cast date '64 block I've recorded.

rexus31, your EUN now the 2nd highest.

Roughly, the Engine Plant assembled about 2500 engines every production day or about 50-55,000 every month.

From other records, I would say that the Engine Plant was up to about EUN 590000 at the end of June (with 06E Time Built codes at Pontiac, others going into July builds). If I'm correct, then they assembled at least 23,000 engines in July. That would be the equivalent of about 9-10 production days. Typically about 1/2 of those engine assemblies would have shipped to the various satellite Plants while the Pontiac Plant took the other half.

So it is conceivable that '64 engine assembly stopped around July 15, foundry production of '64 blocks stopped around July 10 but Final Assembly continued to around July 31.

If so, Final Line production may have dramatically slowed in July. A normal month would have been 25,000 cars churned out of the Pontiac Plant alone and another 25,000 combined from the satellite Plants. The slowdown would make sense as by the end of the model year buyers were either looking for close out deals or waiting for the new model year. No sense for dealers to be building a lot of inventory in July. Even with the GM strike in Sept. looming. In July, that was yet to be a certainty.
