Why does everyone think the pulley drop is GOD?

A tuned GTP with a u-bend delete and a fenderwell and a T-Stat will run circles around one with those same mods and a 3.5" minus the tune...or hell...a custom tuned BONE STOCK car will eat a 3.5" car for lunch. Get supporting mods before being ignorant dropping pulley sizes. Buy headers up front and be done...that way you wont have to pawn off the PLOG/DP when you need more flow.
