if you install an HO in to a pickup that did not have an HO it would not run well, would it?

I don't see a problem, really. If it's an EFI 5.0, they both use 19-pound injectors....worst case, re-use the stock truck cam. I would insist on using the 302 EFI intake, and porting the lower, as it's a phenomenal unit....and toss on a set of headers. I'm tossing around the idea of maybe buying a 1988-1992 Bronco (before the E40D), and using my 306 stuff with that instead, as I need a 4x4 around here for at least 6-7 months of the year....I'm sick of the near-death experiences I get every time I drive my peg-leg 2wd Astro van around in the snow and ice due to the back of the vehicle sliding around everywhere, even with studded tires and a ton or so of extra weight in the back....
The problem you're really going to have to deal with is where to put the knock/detonation sensor, which goes onto the passenger side of the block truck; it's not used on a 5.0 car. I have an idea as to how to make it work....

of course it would if you did it right..Give a man a fish and he will be fed for a day. Teach a man to fish and he will promptly forget that he once did not know, and proceed to call anyone who asks, a n00b and flame them on the boards for being stupid.

EFI engines in the trucks are already pretty close to HO spec's
I am not sure I would use a HO cam in a truck motor, but they are fairly similar so it should work. the only thing that changes is the ignition firing order between truck and HO cam.
If its an 86 Y/M truck, it wont have E7TE heads, but it should have 19lb injectors.
E7 heads (or something better) would help wake the motor up.
Keep the stock Truck ECM since its batch fire instead of SEFI... pretty sure the pin outs on the HO (car) ECM are completely different from the truck ECM.2003 Town Car Signature - 3.27 RAR, Dual exhaust and J-mod - SOLD 9/2011

This is all great info, but the question still is,
If an HO motor is put in a non HO truck will it run right as it is? Or will it need mods?2000 Grand Marquis LS

Be interesting to hear how the truck ECM deals with the bigger cam.2012 Mazda5 Touring | Finally working on the LTD again!

Honestly... the HO cam is not much different from the truck cam.
The spec's for the 5.0L Truck engine are;
Int. Lift -- .422
Ext. Lift -- .448
Int. Dur. -- 256
Ext. Dur. -- 266
Lobe Center Line 116
That compares with the following spec's for the 5.0L HO engine;
Int. Lift -- .444
Ext. Lift -- .444
Int. Dur. -- 266
Ext. Dur. -- 277

Lots of things could make it do that, vacuum leaks being high on the list. I also wouldn't figure than an HO motor under stock truck intake and ECM would be a problem. If anything, it would run slightly lean since its got slightly more cam lift and the HO motor has better heads than an 86 would have. In reality though, I seriously doubt it would be a problem unless you were trying to drive the truck like a Mustang.86 Lincoln Town Car (Galactica).
