Lyn, I vaguely remember seeing Jenkin's name on order forms at GK in the old days when visiting Teweles's shop. But don't totally remember.
GK was located in a less than prime area down near the University of Detroit. Don was way ahead of his time when it came to camshafts back then, was not as much of a business man; but sure fun to work with on cam shaft designs. He was a real innovator. Valve springs were an issue, but he was good at working with the stock spring pressures. While Isky was acknowledged as a leader in the polydyne cam profile. Don Teweles wrote his masters thesis on on the polydyne principle and I personally believe he had more to do with it than Isky. As have mentioned in the past, wish we had taken good notes on all the things that were done. Don's were the only cams I ever ran in the Camaros, Ford and the Mopars. Any car I ran always had a GK cam decal on it. Don love to hear stories of setting class records and going to tech teardowns. I vary seldom paid for a camshaft there. Maybe helped pay when a new master lobe was required. Don was a very generous and kind man. |
