cam upgrade for stock 360 with low Comp Ratio
My friend has had good luck running the Comp cam CCA-20-223-3 .477 in/.480 ex in his smog 318 with aluminum intake 625 carb and headers..
Absolutely the largest cam I would run with what you got. I suggest one smaller. A cam with 218@.050 intake duration is IMO a better fit. You can use it with the stock converter. Been there done that.

Lunati, Crane cams, Summit etc... have similar cams.
With the beginning 1300 rpm range, Just a few rpm's over idle, it is within the stock converters ability to cope without issue. By the 5600 rpm mark, you should be flyin!
