Clutch and transmission change, 1994 Mustang GT

Im going to be putting a 331 with a tfs top end package on my 94 gt, (just sent the block off) it should be making around 350-375 at the wheels, the motor is from another mustang, my cars motor now has a little over 143,000 miles on the clock, same with tranny, when i put in the 331 what the hell should i expect my transmission to do???, ive seen a 1200$ FRPP transmission, will this handle my 331, or should i pull the old tranny and have it rebuilt and beefed up?, what about the rear end? 31 spline axles? then i will also need a new clutch, lol right now its a king cobra, its pretty much shot, i can drop the clutch in 3rd gear and it wont die, whats a good clutch that will handle for a good price, i have about 5,000 and i believe the rebuild will be around 4500$ im sure i'll make another couple hundred in time so if i had 1000$ what would be the best thing to do with the drivetrain, also should is a 190lph fuel pump with 24lbs injectors good enough or should i go bigger???

Sorry guy, I just now found this.
You'll be right at the limit of the 24's if you make it to 375. If you do, you can either go with 24's and turn up the pressure, or go up to 30's and turn down the pressure, which would be the preferred method.
If you're putting out that much power, I'd suggest upping the ante to either a Tremec or GForce. 31 spines in the rear if you're entertaining the idea of any kind of racing, and then either a Centerforce Dual Friction or a Spec Stage 2 clutch. This is, again, if you're putting out that kind of power.

Other than a TKO, you may try Promotion Performance down in Florida.

They specialize in "beefed up" T5's, T45's, 3650's, as well as TKO's.
We have sent our TKO's to them to "work their magic" for customers laying down some serious numbers. You can call them at 954-295-1401 and ask for Walt or Wally.
