340 cam
None of the numbers posted by the OP are going to work for Internet searching.
A SB Mopar cam from Comp will have a part number that starts with a “20-“, then a 3 digit number, a -, and then another single number.
For example a 280H Magnum cam is a
20-232-4
If what you have is a shelf cam, the number should be on the cam and the box.
