well i just got the truck back from the shop, had the 4k gsk and laser cut delivery valves. It is like an entirely different truck. The top end power is just unbeilvable, i dont know how ive had the truck without these things, now i know what everyone else is talkn about when they do these things. and now im saving for headwork and then a turbo. Looking at my mods what headwork do u suggest an what turbo would suit me good, hx 40 hybrid or what thanks

 

Sounds like your happy
What type of rpm does your auto shift at? I bought a 3k kit to put in but think I should just go straight to the 4k kit whats your take? Did you have 3ks in there before? I havent gotten much info on the 4k kit with a auto?

 

From what I've heard , get the 4,000 kit , the same just an extra spring that fits inside of the other, the scientific method , one mod at a time to see what each does, if you have the resist doing all at once.

 

i have the 4k spring kit in my truck (auto) and with the goerand converter and valve body it will carry way up into the rpms if i want it to, throw it in first and it will burry the tach, sift it to second and it will bury the tach, throw it in drive with over drive off and converter locked will hit 4k and turn over drive on and your now haulign some serious a$$

 

Hey remember that you should put 60LB valve springs on before you put your foot in it or you might be looking at un-wanted head work before your ready for it. I put them on intake and exhaust but im pretty sure you only need them on exhuast. The head and turbo work i think is kinda a limit on what you want for power and what your want to spend. i mean you could fire ring it and fo 13mm studds and like a KSB-1 turbo and be pretty happy, or you could go all out and do twins.

 

I have no idea what you guys are talking about, but good...I'm glad you like your new mod.

 

silly 12 valves
