I agree with Skip.

Not long ago I worked with Tim Goolsby at Bullet Racing Cams for a new cam in my current 505. Tim worked with Harold Brookshire at UltraDyne for 21 years.

They have have both UltraDyne lobes and their own designs.

Harold when he owned UltraDyne did a lot of Pontiac cams and Jim Butler recommended and sold a lot of them !
Here was a statement by Harold Brookshire:

"Although I have done only a few Buick cams, I have done an awful lot of Pontiac's and Oldsmobile. Jim Butler, famed Pontiac engine builder, was my largest buyer of camshafts at UltraDyne, doing over $65,000 a year.
He thought they worked very well, until the Recession of 2000 left us with an inability to keep him supplied."
