engine swap questions
Ok got some questions for when the inevitable happens and my engine needs to be either rebuilt or what ever, if I want to swap the current 5.0 engine out of my 1995 F150 with one thats more modern (same type) 302, 5.0 are the 2009+ engines (lets just say one buit in 2013 will be used) be more fuel efficent (think direct swap crate drop in type thing going on) then ones built back around 1995 or so?
im thinking if I can take a more modern engine of the same type that will be built with some economy in mind that I could use it and just do the swap and keep my truck as is with a newer year engine...is this even possible or am I just going to be banging my head?

That's DOHC, not DOHV. All modern engines have overhead valves. Dual overhead cams can give you different profiles for intake and exhaust valves. Usually DOHC also give you a pair of intake and exhaust valves for greater flow potential over single valve sets. Overhead cams have the benefit of replacing the reciprocating mass of the lifters and push rods with long timing chains. This give the potential for higher rpm operations.
Production of the old Windsor based 302/5L engine ended a few years ago, so if you get one today, it will most likely be a rebuild. They can be gotten with newer head and cam designs will make them more efficient, cleaner, while producing more power, but they will not come close to the capabilities of the latest Coyote based 5L engine. But the new design will take a lot of work to replace the old engine, as Smalltrucker said.

Just buy a new truck. It'll be a whole lot simpler. The 5.0 Coyote based 5.0 shares nothing in common with the 5.0 you have now. EVERYTHING under the hood will have to be changed and modified to swap. And whatever fuel efficiency you think you'll gain will be eaten up by the cost of doing this swap. You will never recoup the money spent.

A well thought out build of a 302 using either good stock or aftermarket parts will allow you to make over 300 HP with good drivability. You can use a good old carb or use FI.
Going with the current 5.0 Cammer as Ford calls it is a whole different animal! While it's all aluminum it's not much lighter if it is at all. It's much bigger, wider, taller and a swap to one with all the electronics that you'll need will cost around $10K or more.
I can build a 302 for a fraction of that cost using good used parts including aftermarket aluminum heads! Will it make 450 HP that the Cammer makes? No, not without additional mods like adding a supercharge,r which I could do and still spend less then you would on a Cammer swap.
