Unfortunately, the olJeep(dot)com website is down, so here I am Does anyone have the specs for the OEM cam that was in the 1974 401 engine?

I need to order a cam/lifter kit and am going to go with OEM specs at this time. BJs has the Comp Cams 260H and I believe that's the one. Does this look stock?
Specifications:
Advertised duration: 260 intake/ 260 exhaust
Duration at .050 in. cam lift: 212 intake / 212 exhaust
Gross valve lift: .447 in. intake / .447 in. exhaust
Lobe separation: 110 degrees
Basic rpm range: 1,200 to 5,200
Good low end torque. Strong mid-range power. Excellent for towing or performance.
Recommended compression ratio: 8:1 to 9.5:1
I contemplated an "RV" cam, the Comp Cams 268H, but it would entail pulling the heads to do the valve springs. I'll do that when I find a 258/4.2 or a 360 and convert it Iverson to propane. For now I just want to be sure the 260H is going to be the right one. This is a basic refresh along with the timing chain kit and swapping an EB 2131 intake.
