-There were a lot of racing programs from the factory and other Very Mean Supercars, but Motion was available to the guy on the street on a daily basis ---building cars for customers as fast or as wild as they wanted to go.-Couldn't really get any meaner than the 454 VEGA--and then the calvary was called in to put Motion back on the reservation---So for the MEANEST --You gotta go with Motion, welds and all
