Help me please tryin to beef up 318

So that would be 60fts, and first gear only then?
And you want to humiliate the ford guy?
With a 73 Dart and a teener?
And you are still in school?

What did this guy do to you?
Seems to me .... well never mind.
You are gonna need to do some suspension work first. You can beef the heck out of that teener, but if you can't stick it, it'll be a waste of money.
Next question is what are you prepared to give up? And is this a one-time schooling you want to put down?
To do this you just need some ft.pounds.You can do it with motor, or you can do it with torque multiplication. But above all you will need suspension mods. That Foxbody is waaay ahead of the Dart in that department.
