[Spridgets] Bugeye Group..... Plugs?

[Robert E. Shlafer]

The higher the number the more cold with
NGK's.  948 or 1098 normally take "5"'s stock ("6" hot street tuned) while stock 1275's normally take a "6", "7" tuned.

I ran "8"'s on my stock 1275 with Judson blower but these carbon fouled at lower rpm's around town. Too cold for all around use.

So I finally settled on "7"'s as a good all-around for this application while enlarging
the Holley's fuel jet to a .58 for higher rpm
enrichment (combustion process "cooling").

Worked.
