What 340 camshaft?

I've got a wiped lobe. Verified by dial indicator.
Looking for a new cam.
340 engine
Standard bore.
Stock heads(1970 2.02/1.60)
Hooker competition headers with free flowing exhaust.
Eddy AVS-2 650 carb
Electronic ignition
10.5 to 1 compression
4 speed car with 3.91 gears
I'm camshaft ignorant, all I know is that the engine was rebuilt years ago, and the cam was replaced then with an "RV" grind.
