In this video I share an update on Tony Guzzo’s 1968 302, discuss the camshaft selection, and a tip of the day that can help prevent hydraulic flat tappet camshaft failure.

So, if you wait `till you have your heads ported and look at the flow ratio if the exhaust flows more than 75% more likely a single profile, less than and you might just want a dual profile. PS thanks Mr Vizzard
We ran off road z28 cam way back.. but these days I'd run solid roller with .550 lift 248 @050 and 108 to 110 CL
ed pink said it best in a lecture i went to when he was talking to a cam manufacturer he asked if it was worth it to degree the cam the manufacturer asked do you know how ? he replied of course the manufacturer said good but bottom line is unless you grind it your not changing much of anything! you are inspecting it for the most part when he gave that speech i put my degree wheel away and got a lift gage that measures actual lift of the lobe i go through and check them if i look at the cam physically and see something i dont like
Great video. I am looking for cam recommendations for my 327, flat tops, stock cast iron 2:02’s, C3BX dual plane. It’s going into a 63 Chevy short bed, 700r4 with a 2500 rpm stall converter and 3:73 gears. It’s mainly street driven but I am not too worried about street-ability. It’s an old build and has an Engle 267/.460 hyd cam. Thanks in advance.
In 1968 Chevrolet went to a larger journal on the crankshaft, so are 1968 and 1969 302's large journals? I'm not including the 400. It has a 2.65 main. I like the saying RPM tales the place of torque. I'd like to see the head flow lift by lift when you are finished with them. I believe that is the only way to choose the right camshaft
