I'm wondering if anyone has tried using some higher ratio rockers on the 6.0 with the stock cam for more lift, and if so which brand and ratio and results?

Any issues with valve train geometry being messed up?

 

I've run SLP 1.85s on a 5.3 gained about 10hp.I'm going with a cam and shaft mounted rockerarms on my new setup if you need a set I'll have a set for sale in about 2 to 3 weeks.

 

I used the SLP 1.85 rocker arms on my 6.0, they knocked off .15 on a G-tech in the 1/4 mile. The only reason I got them was b/c I bought a predator programmer and was not satisfied with the performance it gave so I returned it. Luckily Tbyrne was kind enough to let me use the cash from the predator towards a G/P he was having on the rocker arms, I knew I would get some kind of gain from these unlike the predator.
