im running the tsp 224r cam currently in my 5.3 With the added duration of the 228 i would reccomend no less than 3600 stall. I run a 3200 and it runs fine but i think it would've done better with a 3400ish.

that cam is going to want some more intake flow too. look for some ported heads to match and a tbss manifold for optimum performance. i would go smaller on the cam otherwise if you plan on staying with stock heads
