Don Teweles at General Kinetics, along with Joe Lunati were pioneers on dwell lobe Stocker camshafts in the early days. Cam Dynamics also created many Stocker dwell cams that were crazy fast too.

I am confused? The cam in my 396/325 BBC has that "'square lobe" being only a .398 lift cam too. Isn't that due to the duration in the cam? So if you had too use Stock durations back then..how could they have square lobes? I was thinking they changed the LSA from stock for more overlap..
