throttle cable

this may be a dumb question, but its worth asking. i did a slant six to 360 swap in my duster. i used the /6 throttle cable. is it the same as the v8 cable? its a lot longer but i was wondering if it allowed for enoughh travel. ive had it on for awhile, it works sorta ok but i had to jimmy rig it to work. and i also dont tink its allowing the carb to fully open to w.o.t

thanks
