want more ponies, rockers arms?!?

[RNS]

Just curious if any body is running different ratio rocker arms/how well they work, comp cams seems to have a good set up. Also were do you fnd the engine code to figure out what pushrod size you have, i.e. 5/16 or 3/8. Or you just have to pull the valve cover and measure? Oh BTW i have a 2006 HD 6.0L

I put cane full roller rocker in my 2004 GMC sierra 6l with 1.8 ratio the stock ratio is 1.7 it may a difference in power and gas mileage.
I not sure about ths size of the push rods ithe kit I order from Jegs came with new push rods which were a little larger but everything work just fine.

Hope this helps.

Hey, so ya know the 8th digit of your VIN is your engine code. It might still be a U for the 6.0, but maybe different now with all the flex-fuel stuff. Good luck.

I just put 1.8 rollers on a 2000 Silverado 4.8. Made it sound a bit more choppy and gave a little more power, but I wont be buying any for my truck. Wasnt worth the time or money IMO. The stock rockers are really not bad at all. If I were you I would go with a set of longtubes and an intake if you dont already have that.
