Fixing vs. Buying a New Engine / 273

So, a little bit of an update. I didn't end up getting Mad Dart's 340 as I was really unsure and busy with school that week so he sold it to someone else. However, I'm still sort of on the hunt for a new engine and am curious as to what I should look for. I'm looking for a 360, mostly for cost and ease of installation. I'd rather have a 3rd Gen Hemi or something else but you know how pricing and labor intensive that can get. I think a fairly stock engine should be fine (kind of want to keep costs on the lower side). I will most likely want to convert it to something that's carbureted as well (for simplicity and cost's sake). I may be wanting to add boost to it as well. That being said what kind of 360 engine should I be looking for? I believe the magnum engines came out in '92-ish. Would it be best to go with that or an LA engine? I see Magnum engines pop up occasionally for about $500 or so. I know I'm probably going to need a motor mount, intake, carb, air filter assembly, and oil pan to swap it into my Dart.
