Barton brought pro stock tech to SS/AH when he hired some of the best pro stock minds to help improve cam and valve train issues. He started it and it really took off. The last couple of years before Jenkins passed he contacted a well know GM racer and talked him into letting the Grump build some SS/AH motors. Jack Roush was involved a short time in a blue & silver Cuda. Nickens built some power plants for a Texas AH racer and now with Reher & Morrison and Jason Line in the mix, where will it end.
