That is what I did first. Then I thought I could use the Fitech return spring if I moved the cable up to provide more leverage. Turns out the Fitech throttle travel in the high hole is 2.56" while Holley carbs in the high hole are 2.1". Early A-body cables max travel is 2.25". The cable pull tension with a Holley and factory return spring in the high hole is 4.75 lbs. The Fitech in the lower hole is 8.3 lbs and in the top hole is 6.7 lbs. I'll probably end up going back to the Fitech return spring removed and use the conventional return spring. I was just wondering if someone has come up with a solution I haven't thought of.
