Fun to see the 340 Camshaft specs here and the engines they were used in.
340, 4 bbl, Hydraulic, 430/444, 268/276 (automatic camshaft)

Surprised to see the '70 340 Six-Pack used the same automatic camshaft.
Also the 318, 4 bbl too.
360, 4 bbl engines too.

Like that they threw in the 318 Roller Cam comparisons in there too.

Here is the:
340, 4 bbl, ‘68 Manual Trans, Hydraulic Camshaft specs
444/453, 276/284

Those specs look like what is published in the service manuals... I'm updating a spread sheet that I put together for my own references, but when I originally did it, I didn't have all of the good years of service manuals handy... Now I have pretty much a full set ranging from 65 to 76... I am only up to reverifying 65 - 67 and I need to keep going, but time is short for me right now....

Plus I got myself side tracked on putting together a torque spec chart for engine bolts as I do the camshaft specs...
