My suggestion:

Go with the t-5 tranny, and get the 3.73 gears, trust me, with a five speed, you will regret 3.55's. Forget the 4-10's.

Forget the archaic carbed motor. Get the best of both worlds. Find a 5.0 out of an 89-93 mustang and drop it in, fuel injection, computer and all. Those motors are already pushing an honest 225 horses. With the fuel injection and computer you will have great reliability. You will find out real quick how back carburators suck when having to drive them every day. WIth the 5.0 motor, you can get all the mods that the "fox" cars get. Such as an edelbrock performer intake, gt 40 heads, etc. Then when your dad says "ok" you are good for more power, then time for a supercharger. Why build one engine just to get used to it, then build another a few months or a year down the line. Start off with one engine that you can take all the way.

Do you really have the dough for this? Sound like an expensive project to me.
