My old man has a 03' silverado 5.3L 4x4 sb ec and he wants to install a cam that increase the truck's torque.

I've been searching and I found this 2:

Crane Cams: 208/216 .500 lift 113 Degree Lobe Separation

Comp Cams: 206/212 .515/.522 lift 112 Degree Lobe Separation

I guess comp cams is the best choice, but I really don't know, any of you had tried one of this? dyno #'s?, track times? hauling?

Is there any other good choice? (crower, lunati).


Thanks in advance.

 

Of those two, I'd shoose the Comp. If you are going to buy one new, talk to a sponsor and get one custom ground. A sponsor will help you get what you want out of the cam. You will be able to pick out all the specs and it won't cost you any more $$$ than the other ones.

 

Call MTI, they will say something in this range 208/212 560 lift.If i had it to do over i would have went with something like this in my 6.0 instead of the comp 212/218 522/529, Although MTI might recomemnd something a little less for the 5.3

 

Thanks for the info guys.

I guess I'll call the sponsor.
