Can you post a picture of the hipo crank washer next to a non hipo for comparison?
-
Don't have any stock 289 washers to do so with but the Hipo is different then the standard washer and makes up the difference in balance of the motor also.Most people who know Hipo's know the difference!

Great so you don't mind posting a picture and some dimensions of the one you have for sale?
-
I would be curious of the dimensions of the washers that you have, just for the record. Pictures would be nice too.

I'm curious as to how a crank bolt washer has any effect on the balance :o
-
Ford put a Bulletin out on the size,thickness and weight of Hipo balancer washer.The balancer,bolt,washer and cookie cutter all played part of balance along with flywheel and Hipo rods.If your just putting a motor together without balancing it good luck as we don't do my motors that way and never have.There is a difference on thickness and weight of washer from standard washer.That might be good discussion for someone else to start a thread away from the classifieds!

You sure are being evasive, just saying.

It was my understanding that the washer did not have to do with balance but was a safety factor to hold the balancer secure at high RPM . A respected SO CAL engine builder Ford guy Randy Gillis told me "Ford engineers felt that the higher rpm potential "could" allow the thinner washer to deflect and lose clamp load on the bolt and eventually fail."

My August 69 Ford Parts Book update lists this washer for the 289 spec. as part # C3OZ 6378-A. It shows the dimensions right in the book as 1 3/4" OD, -21/32" ID, - 1/8" thick.
For all other applications the standard washer is part # B8A 6378-A. These dimensions are 1.76" OD, -.77" ID, .212" Thick. This is correct--The standard washer is thicker.
This topic has been bothering me so I crawled under my K-Code and removed the bolt to double check the washer. It measured exactly with the parts book dimensions. Now I'll go back and torque the bolt and washer back in. Hope this helps out my fellow Mustanger.

C3OZ-6378-A is .32" thick versus standard size of .21" according to Bob Mannel's book, page I-4. A side by side picture comparison is on page 3-14 caption (F).
And there is no way it could have an effect on balance.

Go balance a motor and tell me if the difference in size which effects the weigh makes no difference in the bob weight...ya right!
-
To say that a tiny, or any difference for that matter in crank bolt washer weight would change the balance is pure nonsense. Uniform thickness, and diameter. Spinning around itself. Think about all the different pulleys that were used without adverse effects over the years. Single groove, double, even triple. They would make over 1000 times more difference than a small washer.

Let's be blunt. It is a fact that Ford sold replacement parts, identified sometimes as NOS, that were not the same as original factory. It is a fact that there are unscrupulous sellers since the beginning of time. If a potential buyer asks a pertinent question about a part, the seller should provide an appropriate answer. To the specifics - there is more than one crankshaft bolt washer. Many of us that are fortunate enough to have a 64-67 Mustangs with the 289 HP engines know what the differences are. Others do not. That is the whole question. You put up for sale a specific part. A question of authenticity was asked. You got evasive. The thread got a bit off topic about the specific design of the washer. At last count there were three thicknesses mentioned. All you needed to do to keep this thread under control was to provide a thickness of the washer. You did not. Now you try to "sweep it under the rug". Why?
