THROTTLE CABLE QUESTION

I found this throttle cable stuff to be a challenge when I was building my avatar car. I have a 408 with a Holley 850 DP and a Super Victor intake. So I tried several new cables (bought from Summit) and some I had laying around. I made a little cartoon and measured them up and put the info in a chart. You'll see the one I ended up using as noted in the chart. (Round vs square means the fitting at the firewall - round has the clip and square has the plastic "pop-out" legs that hold it to the firewall.)

This is the throttle cable bracket I used (also got from Summit):

I hope this helps and doesn't add confusion!!
