3.4 or 3.25??



2000 GTP with custom CAI, 180 stat, one range colder plug, ubend and resonator replaced with straight pipe. Florida heat!!

Which pulley would be better for a daily driver with the mods above?
A 3.4 would run fine with the mods you have.

When I went to a 3.25 I had to add Water Injection to keep it from knocking so bad here in ATL. If you are in Florida you may run into some problems running that small of a pulley without some type of cooling.

Good luck!:)
