Swapping spindles for rack & pinion

This is for a drag race setup, suspension travel limited. I recently went for a ride in a car that did this. Car runs 8.80's in the quarter. The builder builds 4 second RVW cars and Pro Mods. Swapped early spindles, pinto rack mounted correctly with some mods to the width of the rack, and you didn't feel anything funny unless you were in full lock steering. A drag car putting around in the pits isn't gonna be parallel parking. Guy said he'd having his same chassis dude do the same thing on his second car. Lol I'm also aware many people find it hard to say "I messed up", that's why I'm searching for actual people who have done this.

I'm very, very knowledgeable on how steering systems work.

Actual experiences, please. And modern, if possible. Alot has changed since the Direct Connection catalogs...
