I would get the 3.4 if you do alot of driving. The smaller the pulley, the more knock you are gonna get. Which is bad, you should think about getting cooler spark plugs and once it gets warm, get a 160 degree thermostat. You also should think of making a fender well, or cold air intake to keep temps down as much as possible.

It would be smart also to get a scanner to make sure the knock stays down.

I have a cold air intake from trackracing and Costom mangaflow mufflers will that help?...by the way ive never felt any knocking in my car before ...at least I dont think so....but one time I put it in 1 and then floored it and heard loud banging on my motor...is that knock?

Check your PM's. It is possible what you heard was knock, the computer recognizes knock and retards the timing to keep it down, but when it does this you are also loosing horsepower.
