Re: 67-72 motors available 4x4 Chevys Trucks

Special K, I was refering to the motor being stock for the year motor. I know that there were no BB 4x4's. Sorry if i wasn't clear.
Back when i used to mud race in the EMRA we were allowed to run any motor as long as we could pull 14lbs of vacume. External bolt on's were allowed. Up to a 36" tire measured side to side.(some guys would run 38's and air them down. So they put a stop to that.) The truck had to be registered , inspected, and insured.
