It is based on a Dragmaster frame. Just do a search for Jim Nelson or Dragmaster and there will be plenty of information. The Revell Part Pack frame was a Chassis Research frame, another producer of off the shelf dragster frames in the mid century period. MW
Here's my favorite version of the Old Master. I built this 10 or 15 years ago using the Tony Nancy 1/16th scale FED by Revell and the 392 from the Aurora Racing Scenes series. Bruce Wheeler and Al Friedman were my heroes when I was a youngster and I spent a large portion of my adolescence hanging out at the speed shop where they worked. The model was on display at the NHRA Motorsports Museum for a number of years, along with my modest collection of Wheeler Dealer memorabilia.
I even lettered my pickup as a tribute to that shop
