Big block kickdown substitute.

i had a 1965 300 L, 413, 727. and i did not like the shift pattern. it would shift shift at low throttle, and long shift at high throttle. so i lengthened the bell crank link at the fire wall, that is on the rod from the carb. this slowed push rod to the trans. this got the trany to hang in gear at low throttle, and short shift at high opening. this worked for street driving. cause with that big engine i didnt need lots of power at high RPM, for street driving.
