HEI ignition

But dumping the computer is a lot of work to get less fuel mileage and frequently less power. So you've got to REALLY want a non-computer engine to even think about going that route. Otherwise rla2005 is right on, no reason to go HEI.

Assuming we're talking about a stock 5.0L here, I'd suggest a set of Motorcraft 42C's (SP450's) or a set of stock heat-range, copper NGK's (6945's).

Spark Plug
So you recommend copper core over platinum? I thought platinum was supposed to increase hp, and fuel economy. And yes, I do have a stock 5.0L.

Yup, don't fall for them craptastic marketing scams. Everybody says their spark plug are better than the other guys, will give you more power, more fuel economy, but in reality these older engines are happy with copper plugs.
I mean come on... look at this ridiculousness (funniest one yet!):
Pulstar :: The world's best, most powerful sparkplug.
Capacitors in a spark plug... really? You can only get out of a capacitor what you put into it. Which generally means slowly charging it so that you can get a rapid discharge. Not happening because the coil is basically acting as a capacitor already, so you're charging a capacitor with a capacitor (not really but same concept).
I run Autolite coppers in all my Fords. Even my 4.6L Thunderbird got 'em and I've never had a problem with any engine related to the plugs I was using. Yeah I might have to change coppers more often, but to me that's a GOOD thing. Do you really want to leave plugs in for 100K miles and then hope they come out without breaking? I don't. And it gives me a chance to take a look at what's going on inside the engine by looking at the condition and color of the plugs, so more frequent inspection is an added benefit.
The only "benefit" to platinum plugs (and they ain't pure platinum, they are platinum COATED) is longer service life which is not a benefit to me for the reasons above.
If you want a hotter spark, then set your gap bigger (within reason) and get a hotter coil.

What about the Accel U-Groove, I mentioned earlier? They are a copper core. Do they have any kind of advantage over the rest? I found some on Ebay for $2.99 each (about the same price as most of the good copper cores). Where as they are $4.25 each at the local parts store.
You are not going to see a gram of performance or MPG gains other than the simple fact your old plugs may be old and in need of replacement. Simple, cheap copper core plugs are proven to be the best bang for the buck time and again on these old trucks.

If you're looking for a longer service life, then a single plat plug has its place. I'd suggest the Motorcraft 42P's (SP502), which list for $2.26 each at RockAuto.

Where are you shopping? RockAuto has the NGK 6945's for $0.92 each, the Autolite 25's for $1.06, and the Motorcraft 42C's for $1.42.

Nothing in particular buddy. If I offended you, I'm sorry. I spent 14 years in the U.S. Marine Corps, before I got my disability. Through all them years, until recent, I was always partial to Dodge. Everything I know, I know about a Dodge. Hell I even worked for Dodge for 5 years as a Mechanic after I got an Associates Degree in college in Automotive Mechanics. I just recently changed over to Ford, because the Dodge gas tank got to rich for my pocket. I was just trying to compare what I know, with what I don't know. But, you can rest assured, I'll drop the subject of the spark plug, right now.

you already have a high energy ignition,I mean it shouldnt have points and a condenser in it,that went out in the 70's! So what many people do to the 302's is to livin up the stock system...This includes a hotter coil,bigger spark plug wires,bigger spark plug gap and a timing bump also called the six liter tune-up. Many people have done this to their 302's from mustang guy's to truck guy's and everyone swears by the copper cores! Here is a link ......ignition upgrade and timing bump (no 56K) - FSB Forums
