We often hear the word Stealth used to identify a Callies crankshaft. This is understandable, since the very first days of Callies Performance Products the word Stealth has been present in both our big and small block Chevy forgings. In the early years of Callies, the word Stealth gave our product a trade name. It was also strategically placed to allow Tech. Inspectors an easy way to identify the crankshaft’s source and if it were billet in origin.
Callies Performance Products began manufacturing crankshafts for the performance market over 25 years ago. By today’s standards CNC machining in the mid 1980’s was very fundamental. Significant advancements in CNC programming software, computer memory and processing speeds have given us capabilities that had been unthinkable during those early years. These continually advancing capabilities and the never ending quest for product improvement have brought us today to the point of a fully machined crankshaft. For the most part there are no (As Forged) surfaces left on our current crankshafts.
To this day, our forgings have the word Stealth formed into the #1 pin arm just as they have for the past 25 years. The Callies Stealth crank lives on, but in today’s highly refined condition the original trade name is no longer visible.
Your crankshaft regardless of age can easily be identified by the Serial Number stamped into the face of the number one counterweight. Callies maintains a complete process history for every crankshaft produced over the last fourteen years. We can easily validate the authenticity of any crankshaft produced in our facility. Call us anytime to verify that your component is a genuine Callies Crankshaft.
was wondering if I can get the compstar comet crank 3.625 2.100 pin and 400 main size
James,
In the Compstar Comet, we do not. You’d have to buy a Magnum crank for those measurements.
Thank you,

Best regards Stefan
I have a Stealth crank with the number #29397 and a #71.
Any info please. Thanks
Frank,
The S/N you listed is from 1997 or so. We only have total recall back to 2000, therefore cannot give much info based on the SN. If you’d like us to try to identify more about the crank, you may send some images to marketing@callies.com of the cranks’ post, flange, first counter weight, and a full image of the cranks. We may be able to help you out further then. Thank you.

Hi Thomas, One of our guys will be emailing you soon! Thanks.
Your crankshaft catalogue refers to “cammed for rod length” i.e 5.7 or 6.0 inch conrod length. What does cammed for rod length mean and what is the difference between cranks for 5.7 inch rod and 6.0 inch rod. I havent yet decided which conrod length I’m going to use but I know the stroke I want is 3.48. Its a small block chev.
Hi Tony,
We will be sending you an email soon! thanks
I would like the info on cammed length. Can you use a 6.0 rod on the cammed length 5.850. I can see why shorter would cause issues.
