Hey guys, I got my 2002 sierra where I want it in the looks department and am now upgrading under the hood.

I have a 5.3 with the small valve heads and was thinking about camming it. Looking at the tsp220 or tr220 cam (which is better) and longtubes from calspeed most likely. I don't want to do a stall because it is a farm truck primarily and I do tow heavy loads.

Would it be worth the money for the gains I could get with just a cam and headers? Is there another cam you guys would suggest instead? my truck is lifted on wide 32s and gets around 13mpg right now. Also, would efans be a worthwhile upgrade, does it free up more power?

Just looking for opinions on camming without a stall because I don't see many other trucks done up like I'm thinking

 

You dont want a cam like that for the stock stall and "heavy towing"

It will be worse than the combo you have now.

Some 4.10 gears and no bigger than 212-214 intake duration at .050 on the cam.

 

 

yea maybe a 212/218 and the very most.

 

Got any specific cams for me to look at. what vendors are the best, have the best lobe grinds? And would 112 lsa still be good, because I thought lower lsa moves the power band lower too

 

x 1,000,000 this is the cam ur looking for....
