Can't see the forest for the tress... 
You'd probably have to be a drag racing fan to know Prudhomme, but if I had to hazard a guess Zilla's tattoo and Prudhomme's snake probably date to the same general late 60s through the 70s timeframe.
That particular snake was drawn on a flight from SeaTac to Hong Kong, departed Jan. 11, 1970, landed Jan. 13, 1970. (Can you guess when my birthday is?) The artist was one of our group and we decided to use the 18 hour layover in Hong Kong to get matching tattoos. Pinky's, the best tattoo parlor in eastern Asia, did all of them in exchange for the original print.
There's only one of them left now.
