64 Barracuda pace car?

If they could hit 140 with a 273 that’s impressive.
I would’ve thought on a high-bank oval the pace speed would be over 100.
I drove my 69' 340 Dart Swinger (stock) on the Daytona Speedway about 25 years ago (actually twice). It was perk, being in the car show. Had to go around 40-45 MPH or felt like I was going to slip down. Walking on the banks was a chore. To be a 100 MPH, the banks must be steeper now.
