Bias ply slicks vs drag radials

Craziest thing I ever saw with radials was on my buddy’s big block Chevy Camero. It consistently ran 5.90’s on a 14-32 slick so around 2019 he jumped on the bandwagon when Nicky Thompson released their bigger radial (I assume it was the same size as his slick). A four link car he was soon running 5.70’s but not without a learning curve. I was standing around 50 feet from the track but could see him approaching the starting line. I heard one of the two cars spin like it floored it in a rainstorm and turned to look at his son. He looked at me and said yep that was Dad. He Dad passed away a little over a year ago from Covid and his son sold his dragster and races dads car now. I will have to ask if he’s still on the big radial. The guy that races a 5 second Pontiac from the band Trainwreck (Lou Greco) tried them and couldn’t get them to work.
