96 mustang gt, stock motor, hypertech tuner, k&n cai, and flowmasters. Should i do pi head swap and blower or nitrous? I found a really good used vortech v1 with pretty much everything for 1200. What do you all think I should do? I want 400 rwhp either with a blower or nitrous. If i go heads and nitrous ill also go with comp 270's.
