Vortec MAX Posted November 15, 2008 Report Share Posted November 15, 2008 Um... that's the stock rocker for the LQ9 engine. If you have an SS, then you have an LQ9, so that would be a stock replacement for you. Mike Quote Link to comment Share on other sites More sharing options...

mike1booth Posted November 15, 2008 Report Share Posted November 15, 2008 is anyone doing 1.85 rockers as a bolt on? Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted November 15, 2008 Report Share Posted November 15, 2008 is anyone doing 1.85 rockers as a bolt on? not really, you shouldn't need 1.85 rockers unless you have a high lift cam..... Quote Link to comment Share on other sites More sharing options...

Fireman31 Posted November 15, 2008 Report Share Posted November 15, 2008 what is consider a high lift cam? I believe anything .600+ lift IMO..........in order to use 1.85 rockers, you will have to change the valve covers also.... Quote Link to comment Share on other sites More sharing options...
12'SROCK Posted November 15, 2008 Report Share Posted November 15, 2008 FWIW. . .anything other than the stock 1.70 rocker ratio is NOT recomended for cams with agressive cam lobes at all. if you do a cam swap there is no need to change rocker ratio as that method is a cheap and inefficient way of doing it Quote Link to comment Share on other sites More sharing options...
