3GSK or 4GSk?
I got the 4gsk, .imo you mise well. depending on what you are gonna be doing with it. my truck never sees past 3500 and im not worried about the heavier valve springs. i love the throttle respnse. go with the 4 and then when you decide you want to take er there you already got it.. just my .02
yeah thats what my local shop guy told me, i was just getting a second opinion.i guess it always better to have, then not have when needed

ITS AWESOME. totally makes the truck fun to drive. I got a 5-speed and its a blast. If i had a bigger charger it would be even more fun. it fuels very hard to 3500 then i get out of it cause egts are 1200-1400 degress.. ( ya need charger ) but its still a blast! good luck you will love it
Go ahead and do the 4k, just dont rev over 3000 or 3200 until you get some valve springs. The 4k fuels harder throughout the whole range than the 3k, plus if you go for more hp in the future you want have to worry about it
Do you have an auto? If so go for the 4K....I have never hit even 3K on my auto with it shifting itself but the 4K does fuel harder. If you have a stick still buy the 4K and leave the little spring out until you have the money for valve springs if you are worried about going over.
