Talked to Autolite Tech, and the guy, after listening to my set-up said
the XP 3923 would work for the street, and the AR 3911 for the strip. I
will get the 3923 today. I will sell the AR 3934s if someone wants then.

But you will probably need to go up just a small bit in plug heat
range. Or if you can find one in a very close but slightly hotter
heat rance a Commercial (Heavy equipment/Heavy duty line) plug will
usually stand up better. Autolite is very good and used to make a
Commercial set of plugs for lots of different combinations. Maybe
look in C-60 BBC truck engine line.

Did it by chance foul the number 2 cylinder?

I have been using the Autolite Racing AR 3934 plugs in my BB. The
car is street driven with an occasional full throttle blast. I have
one that fouled and will replace it tomorrow. Do any of you use this
plug and how do you like it? Fouling problems?
