On your car go with .060
.055 or so would be for the SC'd guys.... Us NA'd guys need to stick with the .060

Hmm.. that'* interesting. No wonder my car wouldn't fire with .055" gap, but did a little better with .060." But then actually started with the old rusted *** plugs. Amazing isn't it? How old plugs can go through so much ****, and still work, but new one'* can't hold up to the heat?

All NA'd 3800'* should have the .060 plug gap....

Well i'm running the .05-.055 gap with the magnavox and it seems to run a little smoother than with the .040 gap previously. Could all be in my head though.

Well I know that opening the gap will tend to retard the spark slightly (no idea how much) and require a hotter spark to fire so the gap will make a difference.
That said, I would not trust the Magnavox over .045" but that is personal. YMMV.

I had mine at .060" and I had a really shitty spark [at the coils, not plugs].
If you say that a larger gap retards the spark, does a smaller one advance it? What if I were to gap my TR55s at .045" and cut the tip off [exposing the electrode]? Would that make a difference in anything?
*NOTE* I know exposing the electrode decreases the life of the spark plug significantly, but it'* all in the name of power.. and besides how many miles could it kill off one? They seem to 'work' forever in a properly running engine. My old ones are a testimate to that.
