The GEN 1 owners have been finding ways to make it work for years, and it's all in the cam and how it's tuned.
I even ran my rig with speed density, 14lbs of intercooled boost, 42lb injectors using an inline and dual tank trigger and no FMU. I tuned it myself and it had excellent street manners.
There are many others that have found ways to make speed denisty work (with aftermarket tuning of course) and this is one of them: 8.5 Liters of Speed Density POWER! Pics! - The National Lightning Owners Club Inc

a 302HO cam is a 351W cam
Any of the Ford alphabet cams are not the best setup in a truck regardless if it is SD or MAF. The Lightning guys already start with an advantage, i.e. GT40 heads, intake, factory shorty headers a an aggressive tune from the factory. The rest of us have to catch up to start on an even playing field.
The 5.8L is cursed with a poor design intake and E7 heads. Simple bolt-ons like headers, exhaust and a good tune up with quality parts is a good start.Anything beyond that is going to be diminishing returns without replacing the intake and heads IMHO. GT40 heads can be found for a reasonable price. A Mustang 5.0L HO roller cam is another popular replacement with the Lightning guys, but there are other replacements a little better suited to a truck application. The intake is another story. It's gonna cost you a few $$ to realize your full investment potential. Even with a Speed Density PCM a custom tune will yield the best results.
Forced induction is another way to get some power for a reasonable cash outlay with a stock motor. Just don't expect a stock motor to live beyond a 6-9 PSI boost level.

The 302 HO cam were in the 302 mustangs and any 302 HO , they work very well in the 351 , they are a roller cam so they need all the roller parts and a roller ready block to work in the 351 , the 302-351 use the cams , the HO cam and any 94 + roller cam will have the same firing order as the 351....
