what is the advantage to going to roller rockers or longer ones?

 

It's two totally different benefits. The roller rocker Uses a needle bearing in the fulcruum(?) to reduce friction allowing the movement of the up/down motion to be easier with less heat. The Longer ratio Opens the valve a little further allowing more air flow, Kind of like having a little bigger cam.

 

Yep, for example -

I have a .551 lift cam with 1.8 rockers. The .551 lift is measured at the stock 1.7 ratio, so to get my actual lift you divide .551 by the stock 1.7 then multiply by my new ratio 1.8. So I am actually getting .583" of lift.

 

so if i did this ona stock vehicle, what would the gain be?

 

More lift and some duration. Thats it. Easy way out instead of changing cams.

Advice: Do NOT get an adjustable rocker.

 

i don't get adjustable anything, i'm too paranoid it won't be right if i touch it.

 

Why wouldn't you want an adjustable rocker? An adjustable rocker can accommodate any stackups in other valve train imperfections. Maybe I'm not to bright, please educate me. I have the Crane "Quick-lift" 1.8's on my truck and they are fantastic. Easy to install (if your reading comprehension skills are adequate), lots of power and throttle response, and quieter than stock. What am I missing here?

 

Arent needed. I wont run an adjustable rocker on an LS motor. Ever.

 

just use stockers!!!!!!!!!

 

OH GOD WHY!!! I want a simulated cam!!
