212/218 low lift u need some bottom end with those rims i would prolly do gears to.

 

WOW now the 5.3 paved the way to the 6.2. and i love my 5.3 and the 24+ mpg on the high way

 

Maybe 4.11 gears before deciding for sure to go with a cam. What size tires are on the rims

 

Need more info on your ride. Rcsb, ec, crew? What year? Are you willing to run a looser torque converter? DD or weekend warrior? The 212/218 is a good cam and won't require a looser stall torque converter. But a 2600 stall would help a lot. And 4.10 gears will help as well.

 

28" wheels or tires???!?

 

Magic stick 3, texas giant or the polluter. Bad *** grinds

Your options are limited since you live in ca. You could find a used radix that would give you a good bit of power.
