mass airflow choices
 

i am planning on installing aluminum gt-40 cylinder heads on my 1994 mustang gt, along with a gt-40 intake manifold, and ford motorsport headers, and i'm keeping the stock camshaft. i'm choosing this combination so that i can increase horsepower while maintaining a good amount of low-end torque. my questions are, what size mass air meter, throttle body, and rearend gears should i use? by the way, what is the stock mass airflow meter size? i use this car for daily driving.

I would go with a...
-75mm Pro M MAF (calibrated to your injector size, very important).
-65mm FMS TB with EGR spacer.
-3.73 FMS gears.
