Ok now that I have gotten a bunch of Shelby stuff wrong, I also understood that Shelby overstamped the 427 Balancer numbers in a couple of places with newer numbers for the 67 GT500. I had one of these I sold a couple of years back, so I know it was done, the question is did Shelby do it or did Ford?

The complete 1967 Shelby 428-8V engine assemblies with balancer, pullies etc were installed on the line at Ford. Shelby performed fiberglas body mods and added stripes, seat belts and other parts in Los Angeles.

There were no 390 engines used in production GT500s. That is an old wives tale.

The balancers for the Shelbys were restamped, not Shelby restamped them. Thanks Bob

The 65-67 427 balancers were C3AZ-6312-F (casting number C4AE-6316-E) but the 66 428 PI and Shelby used a C6AZ-6A312-A (casting number C6AE-6316-A). The 428 balancer is easy to spot because it has a beveled back edge. Hawkrod

The balancer on a 67 GT 500 was a re stamped C4AE-6316-E 427. The 4 was spot faced off and a 6 was re stamped. It was then beveled on the front to remove the timing grove. Then it had the timing degrees marked on it which created a need for a very special timing pointer. The C-2 cast front pulley was also used. I believe the intake, carbs., 66 427 distributor, balancer and pointer, valve covers and air cleaner were all installed by Shelby. I will check on it tomorrow.

Two 427 Tunnel ports -Two 428's!

All of the ones I have touched had the 66 PI balancer. I did look in the Shelby parts book and there was no mention of the balancer so it is likely that Ford installed it on the engine not Shelby (anything Shelby installed was supposed to be in the Shelby parts list but of course we know that was not always perfect either).

just as Frank decribes it. I also have a low mount adj bracket that looks as if it was ground a bit in that area to clear the balancer. It may have been on the engine that I have, that had the Balancer on it. Bob

Just checked in the cellar, and my balancer was CASTING number C6AE-6316A (quick check did not find a stamped number), with the pulley casting number being C1AE-6312A. This was a 4-speed non-A/C car, well above serial number 2000. My brothers looks the same, but it is on the engine, and I can not get to it right now. Would not bet my life that this would/could have changed during production.

Royce,



If I am not mistaken, SAAC's current records show six '67 GT 500s have "S" engine codes in their Ford VINs. Four of these are presently thought to have been assembly line mistakes and the cars were actually built with the correct 428 PI engine.


However, my car, serial number 0100, the first production GT 500 built by Shelby American was originally equipped with a 390. It was an "Engineering" car and was used for public relations and was road tested by three different automotive magazines. The 0-60 mph times and its 1/4 mile times are indicative of a 390 equipped car.


The other '67 GT 500 that is thought to have been originally built with a 390 is the "convertible prototype", serial number 0139.


This information will probably come out in the next edition of the SAAC Registry.


Thanks,
Eric

I knew about your car, and did not think the question applied to your car.

The great thing about Shelby and for that matter any Ford product is that there is so much documentation on virtually any minute detail. Sometimes we don't find that detail when we want to, but the details keep coming.

Here's a Shelby related document from the Cougar XR7-G program:

Royce,

Thanks for the compliment on the car. The car sort of falls into a "gray area". It is the first "production" GT 500 built; but it was also an "Engineering" car. The engineering department had the car all the way into 1969. I would love to find out what all they did with the car while they had it in engineering, but do not think it will ever happen.......

That Cougar document you have is a great conversation piece. Pretty neat to have that I am sure.

Thanks,
Eric

A Shelby GT-E would have been very cool.
