I am currently installing a new rebuilt 302 in my 95 F150. With it being new, should I tune it to the standards of this Sixlitre Tune Up, or should I put it at the original?

Does it have a cam? Ive found if your cam is anything but stock then factory timing figures are out the window. Currently i run 20 degrees base and 36 total. But if your engine is more less a stock rebuild then i would think to go with the sixlitre specs as it does provide benefits.

When I ordered the engine, I didn't order stock. I ordered the 302 HD. (Heavy Duty) I asked him what all that entailed. I can't remember all that he said, but, I do remember that he said a bigger cam. And I figured out the hard way (on my own) that it has 5.8 heads.

Id start er with the 13 degrees. Break it in, then bump it up and test for pinging, ypull have to adjust the mechanical advance curve but thats another thread lol.

This weekend installed autolight coppers, Ford 8mm wires, Ford coil, MSD cap and rotor. Huge improvement in idle. I had to patch the red vacuum line from the coffee canister as it broke., very brittle I searched and found a great thread on changing out the vacuum line to silicone, so that is now on the project list.

This thread is anchient at this point but I figured I'd update on how a part turned out. Way back in 2010 I first did this and I went with this Taylor cap and rotor.
Taylor Distributor Cap and Rotor Kits 918233 - Free Shipping on Orders Over $99 at Summit Racing

At the time It was fairly new and untested, well now I've tested it. Its been 5 years and at least 44k miles since then. For the last few months Ive had a intermittant rough idle when cold and lazy starting. About a month ago I first had an issue starting after sitting, It would just crank and crank but eventually once it started it was fine until it sat again. The other day it refused to start. Traced the problem back to the cap. There is some wear on the terminals but not terrible. I cleaned them and the rotor with a wire wheel and got an inconsistant spark. I cleaned the terminals on my original Motorcraft cap (yes I kept it all these years) and put it in with the taylor rotor and it now has consistant spark and runs again.
So the life expectancy is about 44k+.

Things to keep in mind, Ive driven it through plenty of rain, mud, water, and dust and to be honest really pushed it hard quite a few times, so maybe I'm expecting too much from a simple distributor cap.

This is a great thread (I'm up to page 36) and motivated me to join this group. I bought my first Bronco brand new in 86, it was a black XLT 5.0 AOD. At some point I did a full tune up and put in some "better" plugs, it didn't run worth a damn after that. I replaced the coil, TFI, put the original wires back on but could not figure what was wrong. I finally swallowed my pride and called the local Ford dealer tech. He said "What plugs did you use?" It took some convincing to get me to believe the factory cheap-o plugs were the only way to go. I put in a new set of Motorcraft cheap-o plugs and it ran like a top. I'm working on an 88 F150 5.0 now that will get the 6liter tune as soon as I fix all the other wiring problems it has

Here's a link for a good read about ignition wires

Truth About Ignition Wire Conductors

This explains the complexities with modern ignition/EFI systems and why ignition wires are so critical to proper operation. The value of this sixlitre tune thread is all the R&D and experimentation done by so many Ford owners in figuring out the proper combination of parts and adjustments that add such tremendous gains in performance. Back in the days before EFI when wire was wire the only concern with high performance ignition system EMI and RFI was static on your AM radio. Throughout these 119 pages its clear to see how some deviations from what's tried and true can lead to all sorts of problems.

I just put a rebuilt dizzy in and retimed the engine. After setting it approximately 12.5, I plugged in the spout in. The timing went to about 18. Is that about what everybody sees?

Question:

Could doing this timing bump cause a SPOUT error code to come up?

I did the tuneup and timing bump on my 4.9L and never saw any real improvement. It's still there and I haven't changed it yet but probably will. However, the last time I ran codes, I got a SPOUT error code, I can't recall what it was exactly but I remember looking it up and it being the SPOUT.
