Anyone have a good guestimation of what my new car might have. It's got K&N CAI, Flowmaster catback with gutted converter, Ported and Polished heads with 3 angle valve job, underdrive pulley, it has a cam no idea what it is but its deff just a street cam (lobe is barely noticable), and a tune (but no idea idea wat kind). 3.73 gears and a short shifter anyone have any ideas of what I could do next to it. Stuff thats cost effective I dont really have a grand for headers.
Had my car dyno'd yesterday.. I was told HP and Tq was suppposed to cross at 5,250 rpm???
Mine crossed at 4,200? what does that mean..??? Would I make more or LEss if it crossed at 5250?

Kind of what I figured I wish I knew more but the guy I bought it from didn't know specifics. Thought someone might tell me like if it might have at least 350hp to the wheels? Also what would be next for me to do?
