Practically Clueless Newbie Needs Help Getting His Dart Up and Running

I would put a cheap used runner in it. I wouldn't really want to be the driver to have to wear out a fresh rebuilt slant.
I would be tired of it long before and pull it for a V8.
But that's just me.
Some guys luv the slants.

The problem of finding and stashing a parts car to get most of what you need for the swap is more the problem. Around here anyways, we don't have yards full of 40 year old stuff....it's 20. Then the parts car you buy will probably need the Trans and engine gone through anyways which puts you more behind.
