Does this prove David Vizard's 128 lsa formula ?

Yeah and that in and of itself disproves his theory right there. How many big block cars have been outrun by STONE STOCK 340 cars? A frikkin lot. So that tells me those 340s worked pretty dang well just like they were. ....and here comes the "yeah but they couldda been better" crowd. Horse ****. They were great like they were.
Absolutely!
