Don Terrill’s Speed-Talk

I don't post here much, but do compete. PSMCDR is one of the most fun muscle car events on the planet, it's a blast and all the people there are awesome. My '68 Hurst/Olds went a best 12.47@108.9mph last year (we had killer air on Saturday morning). There should be more in it, but it really seems to...

Thanks Jim. I did check it a few times, and it seemed to be repeatable.

Thanks in advance!
