All Plugs Fouling on Right Bank

Good story about a bad situation!

If I'm understanding that right, I intentionally did that once, to add vacuum ports.
Slightly different, I added a vacuum advance port to a TQ that did not have one. On my first attempt I put it up a little high.oops, I fixed it.
On another one, an old Holley, I added a 4-corner idle to it. Well the passages were all there, I just had to put the discharge ports in, and figure out how to put fuel in the circuits.That 750 is still on my engine today.
When I first started experimenting, with adding idle-air to a big-cammed engine, to get the T-port sync worked out, I fabricated a device to add air to the PCV system. Then by calculating the area of the additional bypass air, I then could back-calculate the hole size for drilling twins through the T-blades.At that time, I was still stuck on leaving the factory ignition-timing more or less alone. As time went by,I learned that the factory timing wasn't even good for factory engines;even lawn mower engines have more initial timing than any SBM ever had. Of course, after that epiphany, the holes were no longer required.
Yeah so more rambling.......
