Time for a new engine.
When i changed the plugs I noticed in cylinders 3 and 4 the plugs were COVERED in oil and my truck smokes more than a diesel. 3 days ago the engin started knocking. I think it's time for a new motor. it is the 5.0 and I want to put a 5.8 in it. roughly how lonmg would it take for me to do that? what tools will i need? Anyhting i need to know? The ECM will work with the 5.8 right?

The swap can be done in a matter of hours if everything goes right, and you have EVERYTHING needed. I'd give yourself a weekend or more to do it just to be on the safe side.
Good choice going to the 5.8. There's a lot of difference between that and your 5.0. You'll especially like what you'll have in the low end torque department!

I'd probably prefer your 300 over the 351. You've got some decent low end torque, and you can get much better fuel mileage than with a 351. If you've got something else to drive for MPGs, then go all out with the truck. If it's a DD, you may want to consider fuel cost.

If I knew more about diesels, I'd throw in a turbo 7.3 but I think that swap would be more involved than I feel like getting into.

You need a complete 5.8EFI motor for this swap as nothing but the accessories and brackets will interchange, and it will run on a 5.0 computer but it'll run better on a 5.8 version. I say collect everything you need and give yourself a weekend to complete the swap, there are always seized bolts and stuff that consume more time than you think it would.

I ised to have an f150 with the 5.8 and the E40D, that thing hauled ***. I raced a 2003 mustang with the 4.7 and destroyed him. I miss that truck.

2003 Mustang came with a 3.8 V6 or a 4.6 V8 from the factory.
If you really smoked an 03 Stang 4.6 in a truck with a power-sucking E4OD... that's pretty good. Must've been a regular cab 4x2 cause I doubt my SuperCab shortbed 4x4 would be able to do it. Or the Mustang driver couldn't drive for crap, lol.

Yeah, that's pretty good. I smoked plenty of sports car drivers when I had my truck set up with the 460, C6, 4.56 gears, and 33s. With the gearing, that thing would take off like a bullet if you could avoid wheel spin. 2550 RPM at 55 MPH was the downside to the gearing... Now with 37s it can turn lower rpms on the highway, and I like being higher up.

4.7? Either that guy was running a 289 Windsor or you got your late model Ford engines confused with GM junk.

Yeah sorry but I have to say that the Mustang driver didn't know what he was doing. The modular engines don't make low-end torque like our pushrod engines do, but once you get one wound up it will pull. Not that my 351 is slow, she'll burn the 31x10.50 tires and get moving, but she ain't as fast as my 460 truck was. Which was also stock, complete with air horns in the intake tubes because I didn't know such a thing was hiding in there on those engines. Wish I knew of this forum back then.
When the 351 quits, it's getting a few "adjustments" before going back in.

Anyway back to my first question... i got some input ont he engine swap and i appreciat the information. with it ticking in the driver's side cylinder head, can i just get a new head for that side and call it good? I need my truck this weekend to tow a 5th wheel and I have a friend with a couple junked 5.0s im sure at least one has a good head.
