How much horsepower could i have if...
How much HP and TQ could i have if i had: (plus sig mods)
-Ported/polished Plunem
-Ported/polished Intake Manifold
-Headers Edelbrock w/ Y-pipe
-SLP polished large tube runners
-58mm TB
-#24 injectors
-Serpentine belt system
-SLP Cold air induction (single inlet)
-Probuilt 700R4
Also what do you think my times could be?
I should hopefully have all this done by next summer and was just curious how much of a gain i would have after spending all that money. How much do you think i will be spending on all of of it? Im guessing around $2000?

seein that u have about 285hp right now at the crank thats about 228hp at the wheels right now u should be able to do a 13.7 +/- a tenth or so. if i were u id do suspension mods first:
Spohn subframe connectors
Spohn adj. lower control arms
Spohn lower control arm relocation kit
BFG drag radials
Air Lift air bag in the right rear spring
with this stuff u should see atleast a 1.8 60 foot, possibly a 1.7 depending on ur gears, by the way what are u running for gears? also if u ran it at the track already what were ur 60 foots and 1/4m times?
with the suspension work u could expect to see low 13s

I have 3.27 Posi with limited slip diff. My uncle who is a mechanic and big car nut (also used to own the car) says i should be in the high 13's right now as is (13.96?). I dont have any times on it yet but i am going to the High School drags in may and should have a probuilt tranny, Cold Air Induction (SLP or TGR?), and a air foil with pro sparkplugs and wires. I also have the WS6 performance package. Would i still need to upgrade to get better times? Thanks.
