i got a 5.3 03 avalanche im looking for a good torque cam
its lifted with 37s so im not wanting alot of top end i want the torque
whats the ratio on the stock rokers

summit has 1.8s for 350$ is it worth the upgrade

 

stock rockers are 1.7:1
some cams have a ramp rate too steep to successfully run 1.8's....which wouldnt really make any more torque on your motor to be worth...they would just raise the valve lift at .050"..... rou should call compcams with your setup and ask them what they think...

IMO you should look at the 212/218 low lift cam......but there may be better torque cams out there.

just do some reading. good luck

 

grrrrrrrrr i hate reading

 

I had a 210/218 .551 lift 116 lsa in my 5.3 and I think it is a little too big if you are wanting torque. It really doesn't hit until about 2200-2400 rpms. I needed more torque lower than it gave me. Might be a good cam for a lighter vehicle but not a heavy 4x4.

 

What are you running for gearing? That will make more of a difference then a cam or rockers will.

 

im goin with 5.13s
