What should my next mod(s) be????????????

Like the title says, Im looking for a new mod. flexible on price so give me a couple options. My car is a 1993 ford mustang GT vert with a BRAND NEW roller 351W, Torker II manifold, Holley 750 Double pumper, crane 1.7 roller rockers, F303 cam, Offroad Hpipe, Flowmasters, Centerforce Clutch, 3:55 gears, Alluminum driveshaft, Felpro gaskets, edelbrock filter, hurst shifter.
whats stock you ask? tranny, suspension, headers and anything else not mentioned
 
I'm with Thumper. Based on the engine combo you chose, I assume you're more interested in hauling ass in a strait line than carving corners, yes? In order of importance: suspension, definately. You must be putting what, 300HP to the road at least? Full length subs, especially since it's a vert; and rear control arms. That's an entry level suspension for a strip car, the bare minimum necessitated by the engine you have. Shocks/springs/sways,etc, up to you- but at least get the subs and C/A's. If you drive it like you stole it, be ready for the stock T5 to start going south soon. Start putting money away for a real Tremec, and have fun till this one starts acting up. You may be able to buy it some time with a Pro5.0 shifter, but it's about two bills and won't bolt onto the Tremec later- although they hold thier value well on Ebay. Finally, your engine combo probably justifies full length headers, maybe even with 1 3/4" primaries, although I'm not real familiar with the F cam specs so I can't be sure. You may want to consider a beefier fuel pump too at some point. Good luck!

*Edit: in the event that you do control arms, you may as well do torque box reinforcements while they are out. Cheap insurance against a problem you WILL -not may- have later.
 
salty - what are your goals for the car? How do you use it - daily driver? Sometime racer? What kind of racing? Drag, autocross, road course? Kind of hard to advise you unless we know what it is you're trying to accomplish. As my buddy Stangbear says - I'd take a close look at your exhaust system - seems like that's a real bottleneck with your 351.

Still planning on dropping the 5.0L into the 244?
 
I think the counsel you've already gotten is good -- looks like the suspension and exhaust need attention first. You don't mention what kind of heads are on the car -- if they're the stock 351 heads, you would gain a lot by doing something about that situation.
