How much hp will this give me on my lightly modded 3.1? Will i have to change my springs? I heard from some people this is one of the best bangs for the buck what do you'll think?

CCA-1414-12

computer simulated programs say 3hp at peak RPM.

It should allow the engine to rev a hair faster.


I had a different brand, "same part" I felt nothing on the a$$ dyno.

roller rockers really dont give u any hp not on a mild engine anyway, now something with real high spring rate valve springs and large cam yes ull get a lil more power out of.They do however allow for more acurate valve lift, less wear on ur valve stems, and they offer better range in rpms (i.e) more stable valve train
