so my brother is wanting to replace his cam in his 2002 Silverado with 5.3 it 4x4 and has 4.10 gears stock. he wants something with a nice idle and some torque, he has a cold air intake and exhaust that's about it for mods, and I also have HP Tuner to do any adjustments needed. his truck is a daily driver also. He was looking at z06 cam or the gm hot cam.

 

212/218

 

For a 4x4 I would do a 212/218
Great low end power and will come in sooner than the ls6
The ls6 cam was good but power n torque will come in to late for a 4x4s need

 

GM Hot Cam would be a bad choice, its really does not make good low end and the peak numbers are not impressive either. It sounds fast though...

212/218 low lift is a good choice with LS6 springs for a budget, solid gains across the whole powerband and not be begging for a higher stalled converter.

You could also go with a custom grind...

 

Isky 212/212 .561/.561 112lsa

Has a little bit more lift than the 212/218 and will work just fine with a stock stall. The Isky 165A beehive springs are a perfect fit for that cam as well, and not very expensive.

 

I run the triple 12 in my 4.8L and love it. It runs smooth as hell and makes power over the entire RPM range. I also am running the 165A springs from ISKY and can't complain a bit. I would recommend both to anyone.

 

How far up the RPM range will it pull for you in the 4.8? Im hoping I can get a solid 6000-6100rpm out of it in my 5.3.
