11.2 with stock tires,,10.9 with street legal drag radials. The 8-Speed is an advantage here,, .5 sec faster at least,,in the 1/4 than the 6-speeder,,but having 2 more gears allows a broader torque curve. Amazing considering,,in 1970 a fast NHRA Pro-Stock race car won in the 10's but would never survive idling or even a few miles on the street,(valvetrain would burn up and you would need 114 Octane race fuel).
Chevy and Ford,,,batter up!
