Okay Thanks Guys!
1) The engine is complete, including belts, hoses, the computer, everthing! The truck it came out of is readily available.

2) Will I be able to fabricate or make the 5.3's motor mounts work?

3) The yard will throw in a 4L60E in the deal real cheap (they are going out of business) will this bolt to the motor/flex plate?

4) Will my drive shaft work?

5) WIRING!!! How is this 5.3 computer going to work on my '93??

6) Air intake? Should I rob the stuff off the wreck and make it work for now?

7) My brother-in-law owns a shop and he is letting us utilize his facility this weekend. He has thrown in one of his best mechanics and he will help if needed. This is a father-son project so we are pretty excited. His shop can do it all (including custom exhaust). What are the chances that we can knock this out in one weekend?
