rockers
 

hey guys hope you can help well I have heard if you put 1.40 rockers in on a shock 1600SP you can get a few HP ?? well I have a 1600sp with a header and Jpipes and a 32 pict w/1" spacer would this help or is it better just to save up for something better that makes hp?? also is it better to have a high reving 7000+ RPM or something in the middle like 4000?? and I how far can I avans my Dizzy?? sorry about the spelling too it's not my thing.

Without valvetrain upgrades it will kill your engine in a short time. Dual springs and dual carbs a must. I don't even care for 1.25 rockers.

Save your coin, cry once...do it right the first time.
