Not to be a dick or anything... but is he going to be the one to do the work? I know its your intention to wrench, but is he going to be the one that has to do all the dirty work (research and wrenching) while you watch how he does it? I mean, we don't know you so I'm guessing that if your father is worried that he'll end up finishing a project you tore apart... there's a good chance he's right. I'll be honest, I learned a lot from pops. He taught me a shit load of tips, tricks, and other fine advice. But if I was a father and my son counted on me to do a swap like that (when I didn't want to) then ya I'd be a little pissed. I'm telling ya, get some experience under your belt. Learn stuff with your dad. After a couple years go and use that knowledge to build a 5.0L ranger. It's worth it, trust me. But I can see where your father is coming from. If he doesn't have the time or doesn't want to get into this project then you should make sure you won't need too much of his help. I've been there. When I was 14 I thought it would be fun to take the lawn mower and a $20 go cart frame from a junk yard and mate them. Well, my father knew what he was doing and I didn't. What happened? Well, I wanted that thing done and he didn't have time. Because of this, many arguements arose. A V8 swap isn't cheap. Also, its not a walk in the park. There's a huge difference from bolting another 2.9L in that truck vs. fitting a larger 302 with upgraded cooling and such. Not to discourage you, man. But I really hope this project doesn't turn into fights and disagreements between you and dad because thats usually what results when both people have different ideas of the situation.
