will changing rockers do anything with my stock cam? if yes what should i use and what is the benifit?
update your profile and put year and engine in
It'll just increase the lift at the valve over what it was before, and cause the valve to open at a quicker rate (Comparably). With the stock cam this is good to do, as it will really help the low-RPM breathing & increase low-end torque, which is great for mileage.
Go beyond the "bolt-on".
Will I have To retune or adjust timing using 1.6 rockers?
What ratio can I use simpling bolt on with no major modification? Anyone have any info for simple bolt on ratio and stock cam?
