Throttle Linkage Conversion SL6 to V8?
The slant six throttle cable is going to be longer, and I think the sleeve on the moving portion of the cable is longer as well, which limits the travel - I think.
I used a slant 6 cable on one of my cars because the intake was taller and I need more length. I cut the sleeve down using a tubing cutter and then removed it with a dremel cut off wheel.
Id get a v8 cable and compare or buy a used or new v8 cable and install it. As far as the kickdown and throttle brackets all that stuff is different.
