In need of drive by wire

My wife has a 1966 ragtop with a 289 that she is too short (4’10) to drive. I have been looking for ways to get her into a safe and comfortable driving position. The configuration that gives her the best visibility and comfort requires a steering column change, new seat structure, placement and travel, and power-adjustable pedals. To utilize the pedals, I need a drive by wire system. I cannot find anything that would allow me to convert the drive by cable to drive by wire, so I am exploring new engines. She does not need power or speed, just reliability and, of course, a drive by wire setup. What recommendations do you have for a long block or crate engine? Thank you for all of your help.

The adjustable pedals that Ford has in its current vehicles will fit perfectly and give both my wife and I the ability to drive the vehicle with the push of a button as opposed to a resetting of the cable each time I get behind the wheel. It would be great if I could just set the pedals in a permanent location or if there was some way to make a quick adjustment. I was kind of hoping someone had a workaround for making a Holley Sniper into DBW. I will take a serious look at a Coyote. Thank you for your input.
