From Pontiac engineer Malcolm "Mac" McKellar a driving force behind Pontiac camshaft design....
The 041 was often touted in vintage Pontiac sales literature as the division's first "computer-designed" camshaft. Of that, Pontiac cam designer Mac McKellar says, "That's somewhat true-but not totally.
We used a computer to generate the blueprints, and computer technology was hot at that time, so advertising decided to incorporate that."
He goes on....
" I wish we could have used roller technology back then. It would have cut friction and allowed us to improve performance and street manners, but it wasn't available at that time," says McKellar.
Fast forward in time, it would be interesting to ask if he would use those lobes today designing a hydraulic flat tappet cam. I doubt it, and suspect it would go beyond cutting friction !
