What mods do you have now? If you have nothing but an exhaust then you def have options -- gears, 1 piece Driveshaft, Suspension mods, Clutch, fuel system, tires, etc.

If you're going to be uping the boost and getting all crazy ( I would at first ) then you're going to have to fordge your bottom end or else your asking for trouble and flirting with danger. Your factory interals will do decent for a little while but I wouldn't recommend going or pushing pass 450 RWHP on a stock bottom end. I'm not all that sure that I would spend the money on new heads either as apposed to getting my stock one ported 30 over... if someone knows a significant differance bewteen buying new and porting please chime in... however I think porting is the better value though... either way there are different stages of porting so you need to figure out your goals for your stang and what you want to accomplish before hand. ~ J

 

Right now I have coil over set, 18" wheels with 275s, full exhaust, and CAI with tune which I know wont help my S/C. If I was going to go with new fuel pump and injectors should that just wait till I install the S/C or can that be done now? I saw some1 else mention a stage 3 cam, would that be able to stay on if I rebuild the block with forged internals, or would come out?

 

Yes but remember you have to get a cam made for FI. Remember cams control the opening/closing of valves. Can't have too much aggresive cams or u will loose ur psi.

How much would to agressive be?

 

The thing is all current cams in my honest opinion are all a waste the common grinds they got out there. Thats why most of the s197's you see pushing 800+ hp have stock cams and who ever has cams has a custom grind they will never tell you the specs. I would personally wait sometime for some better cams.
