after i get my truck lowered i plan on makin it a little quicker...this 3.0 just isn't enough for me after driving my camaro everyday. i have a few questions. i was looking at the underdog website at all the performance parts they have and i was just wondering what ones are worth the money. I already have an intake so no need to worry about that. will the underdrive crank pulley really help out a lot? what length belt do I need to change to if i get a new pulley? what exactly does a tuner do? would the roller rockers be worth getting? I know on my car headers was the biggest improvement i ever did but with this little engine wont they take away from torque since there wont be enough back pressure? would plug wires and a screamin demon help out at all together? sorry i asked so many questions just wanna make sure i pick the right stuff to do first.

 

well everything you just said will help. An exhaust would be nice to. The UD pulley has been dynoed to get like 10hp and 10 torque or something like that. the tuner will get you some good power when you do a bunch of mods together. Tthe rockers will help a lot, and the headers will help a lot to but they do make you lose a little low end but help top end a lot. Are trucks don't really have to much low end anyways. So top end is where the engine is happy.

 

ok thanks for the help. so what mods should i start off with? underdrive pulley and electric fan?

 

Not to B!TH or anything, but damn, how many times have we heard this question allready?

Also the amount of things you have to do to get even CLOSE to a 4.0 is ridiculous, not saying thats what your going for, just a heads up.

Do the pulleys and efan at the same time, makes the Pulley install easier with the fan out of the way, go to autozone and get the fan tool to disconnect the fan from the clutch, you get your money back after you return them. Make sure you know what your doing witht the fan before starting, make sure you have enough crimps/connection/wire. I am a perfectionest and a lil OCD so it took me a while running everythin perfectly. (may want to tap in to radio fuse for the control switch on fan witha add a fuse thing, at autozone and radio shack too I think).

I would also get the pulley kit looks a lot better, but doen't do much more, nice belt come with if you get it from UnderDog HERE!

Put a cone air filter on there too, bout 20 bucks and adds some kick to the throttle response and sounds better....

Everything I said could easily be found by searching through the threads though........ FYI..........

 

ok thanks a lot. i did search through some threads before posting this. sorry for making a new one and asking the same questions over. i already put a cone air filter on it too and that did help out a little bit.
