Had a '68 383 4 speed Road Runner I bought new. Always had trouble with the one/two shift. Even had a "drag racer" who ran a Chevy claim he could power shift anything - he couldn't make it shift although I though he was going to blow the motor in the attempt! Finally put a T handle on the shifter - managed to literally pull the hurst handle right out of the shifter body next time (remember, they were held in with spring clips), went right over my shoulder! Drilled a hole though the handle & bolted it in! After that, I had a '68 GTX 440/4 gear, with the old reverse lockout handle on it. Same thing - couldn't get a clean shift to 2nd. On that one, I managed to break the lower shift arm right off where it hooked to the tranny. Had to weld it back up! Supposedly, the "fix" was to take every second tooth off the synchro ring to fix the problem but I never tried it, just got used to granny shifting to 2nd! Don't know if there's any truth to the old rumour that hemi 4 speeds were better.
