302 to 5.0

Ok I realize this might be a stupid question. I just got a truck an 84 Ford F-150 it has a 302 with a 2 barrel. It's 4 wheel drive and I want to get more power and fuel economy. I hope to drop in a 5.0 HO. I reallize they are both 302s but will the 5.0 drop right in and bolt up. I realize I'll need the computer. What else will I need and will it run right with out the tranmission and such. There are thousands of sites on how to get one running, so the main question is will it use the same motor mounts and bolt to the transmission (4- speed [3speed with a greanny 1st])????

Why not just upgrade the engine you already have. Like you said its the same Cu.In. The 5.0 HO weren't really that powerful at all. I think it would be more worth your time and money to upgrade the exhaust, cam, heads, intake etc. on the engine you already have. I think you would gain quite a bit more power then you would be dropping in the HO version. If I remember right they had horsepower somewhere in the low 200 range.

engine swap

The only difference between a 302 and a 5.0 is that the designation was changed when they put the roller cam in the 302. For all intents and purposes, they are the same engine, with exception to some later minor changes. Stick with your 302, its cheaper to build, as you wont have to change over to a computer etc to run it. Just put some goodies in your 302.
Some differences in 302 and 5.0. Other than fuel injection and roller cam.
Not sure of the exact year, but the 5.0 went to a one piece rear seal.
In the mid 80's, they went to a 54 vs 28 oz offweight flywheel, and changed the balance.
A small 4 bbl carb, and headers will put you in the same power band as with the earlier 5.0's.
THey use the same motor mounts but you can run into some differences in flywheels and bellhousings.
Stick with what you have, and play with it.

For what it will cost you to buy a good running 5.0, you can put a lot of goodies in your 302, and probably have a hotter engine to boot.
Im not putting the 5.0 down as they are just a step in the evolution and were a warmer engine from the get go. Just no need to start out with an engine that is only marginally warmer than what you have now.

If you are going to use the front sump pan and dipstick in the timing cover, you will need to plug the dipstick hole in the block. I used JB weld. You will need a early timing cover. If you want to go with a carb, make sure you get the timing cover with the fuel pump mount. Also, you will need the fuel pump pickup for front sump pans. You can use the oil pan rail brackets from the 5.0..

Don't forget the balancer needs to be 50 o.z.

You don't need the computer if you run a carb. You just need a carb style intake.

Run the 5.0. They are way better than 302s. They came stock with forged rods, pistons, and a steel crank. The roller cam is worth it's weight in gold. If it is an H.O. the cam is pretty big. They were .444" lift with 208o @.050. Pretty respectable.
