FYI, matt steins 273 runs 10.05 @ 131.78, with stock volume ports and stock size valves, stock carburetor, also its a light car. true its a good piece. also , theres a 65 b'cuda in stock, runs 12.20, and a 65 valiant in stock, runs low 12 sec passes. just food for thought.
Completely irrelevant to the typical hotrodder street engine build. Matt Steins engine would take 40-50k to duplicate. And running 12s in the 1/4 mile these days is pathetic.
