I'm looking for a cam for my stock '68 383.
I am adding a 4 bbl and dual exhaust with H.P. manifolds.
otherwise it's stock.
Going back into my New port.
I have zero experience with cams.

I was wondering just what the stock specs would be.

I'm looking at a Hughes unit.
They suggested one with a rough idle and poor vacuum, along with rear gar change..
I was not wanting that, power brakes and a heavy car.
What I want is more torque.
Here's what I am looking at.
SEH1016BL-12
lift intake 0.320
exhaust 0.330
duration
intake 210*
exhaust 216*
Is this preferable to the stock unit?
