I should mention, however, the last time I ran was in 1965. The car was a 1964 Pontiac GTO, homologation unit, w/factory prepped 421CI, pinned rockers, 6 2bbl, 4.11 LSD. Lite body model, All interior and padding stripped for weight reduction. Car weighed 270# less than stock, with the bigger engine, a roll cage and fire system.
