5.3 Cam Thoughts?

[BR3W CITY]

You can go a chunk larger if you want to, I guess it depends on your goals for the setup. That cam will work fine, but is not going to produce as "obvious" of a result (or a feeling) that a more aggressive cam would. Certain factors like; what convertor, longtubes or manifolds, stock top end or not?, 4wd? will all have an effect on your ideal cam.

If your looking at a stock convertor setup, 4wd, a heavy suburban, then your best off aiming for a flat power band that comes in early. It'll be the easiest to drive, and the peppiest for a small motor in that heavy of a truck. If you want something that has a more "hot rod" feel to it, you can still cheat and run a low LSA on a less aggressive cam. It'll have that little chug/burble, but not act like a big-cammed/convertor truck around town.
