Throttle cable/gas pedal issues - holley on a 318

Sorry to dig up an old thread but I've been having the same issue with my Bouchillon setup. Mines on a 4150 using it their complete throttle bracket and kickodwn on my W2 408.

No matter how much I've adjusted it I can't get it to go WOT. I was so frustrated with it that I bought an ARE Engineering throttle bracket that uses the Lokar kickodwn. Haven't got around to swapping.

Is the consensus still to shim the throttle pedal? Seems like a band aid but if it works. Don't want to go through the hassle of swapping to the ARE setup and still have the same issue.
