I've been studying the NHRA specs for the 194/230/250, from 1963 through 1972. These only show the lift. The 140 hp 230 is shown as having .335 lift in 1963 and 1964,.332 lift in 1965 and 1966, and .388 lift in 1967, 1968, and 1969. The 155 hp 230 is shown as having .407 lift. The 250 is shown as .388 lift all years it was made.
