GO WITH A CHEVY MOTOR!!!!!!!!!!! You will save yourself HUNDREDS and the aftermarket and parts availibility is much better.

If I were in your shoes, I would:
1.First see if someone sells a kit to do the swap with motor mounts harness adapters etc.
2.Buy a whole car/truck that has a 350 and transmission in it
3.Rip the motor, tranny and wiring harness out (THROW NOTHING AWAY UNTIL YOU ARE DONE)
4.Start cutting shit until the motor and transmission fits in there nicely with at least 3/4" clearance around EVERYTHING.


CARBURETED MOTORS ARE 100X easier to adapt and work on, but it will suck gas and not run as well unless you have someone who knows carbs tune it.

That should get you started
