I could use some advice on doing an engine swap, or at least a rebuild. I'm of two minds here. First choice would be an LS with a new trans. Second choice would be a "new" crate engine. Third choice would be to rebuild the crate I've got. Of course, cost is a factor overall.
Some of my buddies argue that the truck is so original (I'm only the second owner) that I should keep it as close to original as possible. However, I'm leaning towards at least a new intake and a computer driven fuel injection system to improve reliability and fuel milage. Any thoughts would be appreciated.

This is so subjective and personal to each person...BUT I'll throw out my (likely unpopular) opinion because you asked!
it's my opinion that the LS swaps are overdone. They're F'n everywhere. If it were me I'd pull your existing engine, rebuild it and upgrade to the Edelbrock Pro Flo 4 MPFI system. I just installed one on my 383 and I love it.
I doubt fuel injection will really help with mileage that much, however. Remember you're driving a brick down the road
Now i'm sure some LS guy will come on here claiming he gets 20mpg. So if mileage is really your goal maybe thats the route for you.
