"Old School" Stocker Cams

[SSDiv6]

The "square lobe" cam profiles are known as "dwell" lobes. With a dwell lobe, you can basically put a lifter on top of the lobe and it will not fall off!

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.

After Don shuttered General Kinetics, my preferred brand was Cam Dynamics when Glen Steyer's was still at Crane Cams.

Let's not forget that in the early days, although they checked duration, lift and overlap, the OEM's had submitted some crazy camshaft specs too, especially regarding overlap.

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..

Lift stays the same it just gets to max lift quicker and stays there longer until it slams back down on the seat....
