hey guys ive had my 12 valve a little over 2 years and im lookin into installin some governor springs. right now at WOT with the coverter locked in overdrive im spinnin right at 2600. id really like for that to be somewhere between 3000 and 3200. basically i want it to rev higher from takeoff and have a faster top end speed. :D should i go with 4000 gsk or 3000 gsk. any input would be greatly appreciated guys,thanks

if he's not going to run 60lb springs to avoid valve float then run it a little loose so its not set for 4k. same how i ran 5k springs but had them set around 4k.

all you need for 5K is a bottom girdle and big springs,retainers,and stiffer rockers...... will work for short bursts at 4500-5000 rpm for a while.......
