Not sure of what's documented here, but I know an effort has been made to record various accomplishments done with our favorite engine, in Y-Block Magazine.. But to get to the point, I believe an earlier one was missed. According to an article in "Rodders Journal", dated Spring 2019, a modified, McCulloch supercharged '56 T- Bird, owned, prepped & driven by a L.W."knot" Farrington of New Oleans, apparently in 1959 (the article wasn't clear about that date? nor what class he ran in?) at Bonneville, ran a then best of 173.00 MPH.!. Apparently it was featured later in Hot Rod magazine, in a July 1960 article, when previously used as a Drag Car... Later runs in 1961 were done in A.Sports, but with a supercharged Hemi engine. (Mr. Knot was 99 yrs+when the article was written)
