1989 Mustang LX w/Tremec (TKO) and 3:55 gear.

Hello All!
I'm swapping the 'Ole 302 out and need some help with designing the proper fuel injection system for the FRPP 392 stroker build up.

With (450 hp @ 5850 RPM and 450 Ft lbs @ 4000 RPM torque on tap), what would be the appropriate size of these injection components:

Intake manifold
Throttle body
Injector size
Mass air meter

Will the factory A9L cpu control such a massive engine upgrade, reckon?

Any help with this project is greatly appreciated!!

mass air id go either c&L 76 or pro m 77or 80

throttle body probubly a 75mm

injectors - 36lbers

intake - Trick Flow 351 R intake

the A9L WILL controll it...but not good..it will run and drive but you will have your share of driveability probs...you should use the A9L with some sore of piggy back controller like the Tweecer(www.tweecer.com) or PMS from anderson ford motorsports
