Bobby Zlatkin said, " Bill, the rule of thumb I've always used to convert 1/8th mile times to 1/4 mile times is to divide by .65."

Using that formula, the Kier A/SA car's 6.47 eighth-mile time converts to a 9.955 quarter-mile time, which was my original contention.

Apparently, the NHRA uses that formula to convert eighth-mile indexes to quarter-mile indexes, since that's where I got my original numbers.

I have no dog in this hunt; those numbers seem reasonable to me, but, what do I know???

Ed is right about the language that used to be in the rule book; if it didn't specifically say you COULD do it (legally), you coundn't...

Who knows where that went???
