5.0 bolt on installation help
Okay got a 5.0 that I'm dropping into my truck but right now it's just sitting out.. I've got heads,a cam and shorty headers.. So is that stuff I bolt on and I'm good to go or what? How so I need to go about putting these parts on?

Which means it's not a 5.0HO, but that's actually a good thing in this case because the Explorer motor has better heads and intake than the HO motor.
The GT40X heads are a step up from cast iron GT40p heads that are on that motor, not a hugh step but you do get away from the spark plug issue that plagues the P heads. That cam isn't the best choice however, I don't know about this specific cam but most "retrofit" cams are ground on a smaller base circle so that the lifters don't stick too far out of the bores in a non roller block, but your motor is a factory roller motor with taller lifter bores so this isn't necessary and you're better off just using a standard roller cam like the Comp 35-320-8.

Yes those heads are very good, and the cam I suggested is quite a bit more radical than stock so it will have a noticable idle, there will be no doubt you got something other than stock under the hood. I have the sister cam to that one in my truck right now.. all the same specs except 114LSA and it definitely makes good power.. no comparison to stock. DesktopDyno says your combo will make 328hp at 5500RPM.. which is gonna stretch 19lb injectors to the limits so you're gonna need 24's and a tune.

DD is optimistic by 13%, 328hp is more like 286 and barely out of the limits of 19lb injectors at 80% duty cycle. I figure at max horsepower the injectors would be at 84%.
If I had more cash to throw at it I would get that cam, tune and injectors.
If not, I'd run it, but choose a different cam that doesn't require a tune nor injectors.
What tranny does your truck have?

The version I have(2003) isn't if anything it's conservative, for example I can create a simulation for an all stock motor and it produces numbers that are nearly identical to the official ratings. What number do you get with your software?

I have found DD2000 to be over by an average of 13% on stock builds. I find that a stock 95 351W comes-in at 235hp and 377ftlbs.

I asked becasue I'd prefer more low end torque for a standard tranny than the Comp cam makes. An E4OD stock torque converter stalls around 1,600 to 1,800rpm. It is more forgiving for cam choice than a standard tranny. The idea is to get a cam that will produce peak torque at about 400rpm before it stalls to get the best off the line performance. I second The Conanski for cam choice! If you went for a more radical cam then you would likely need a tune and a higher stall torque converter to get the most out of it.
