Is there any hp to be gained by changing from a comp cam 1.6 roller tip rocker and going to a pro mag 1.6 ?
And how far should you adjust the rockers.Gm stated 1 full turn from 0,some say 1/4 turn,some say 1/2 turn,tpis stated 1 1/2,which one is right. The cam that is being use is the lingerfelter 211/219 cam. I do not want to adjust them too tight.

 

You might see 2hp...

I went 1/4 turn past 0.

 

I know what you mean. I ended up kind of averaging all the different answers, and I just do a 1/4 to 1/2 turn past Zero. The rocker adjustment is pretty forgiving though.

 

you will see more then 2hp I say about 7

 

I doubt it because he's already starting out with the 1.6 lift numbers. The only gain he might see is through the trunnions of the full roller rocker.
