With a 3000-3200rpm stall I would recommend 217/221 .605/.609 112+2.
I feel most over cam these 5.3's. I get great power out of my 215/215 112lsa cam in a 5.3 so I feel little need to go larger unless the customer would like a choppier idle.
What kind of power are you getting out of a 5.3 with the 215/215?
