Hi, does anyone know of a dyno shop in the San Antonio area that is capable of tuning a carbureted 440 engine. I have a 850 demon with annular boosters. I had it tuned fairly well with the purple shaft solid lift cam. But have upgraded to a solid roller with less duratoin an more lift . I'm close with the jet size but not sure what effect the Air bleeds & emulsion bleeders I have. It has a stumble just past tip in.
