360 cam question

I have a 65 barracuda, putting a 360 in it. We’re using stock manifolds, after market intake and 323 gears for now. 727 transmission. What cam should or could we use? K20-223-3?

I should mention we want a noticeable idle and the exhaust will be 2 1/4 possibly 2 1/5
You mean 2 1/2, not 2 1/5
