2020 Small Block Penalty Box Race Sign Up

I think a better question is how was the original time figured out of a 15-9 or whatever for a automatic 318 car weighing 3300lbs?...

Pretty sure that was the factory advertised e/t
THat came from the original 318 race I did in 2017. I ran a stone-stock 318 2bbl in a B-body and ran a 15.9. 904/2.94
