full manual reverse valve body -- streetable?

Dusterdon, I can see where a loose convertor and easy throttle would be ok.
Race cars are allways full throttle and a friend had a mid 60's Dodge pickup with a 440 and a manual 727 that he used as a driver and a parts hauler and that thing usually snapped your neck but he was usually loaded or pulling a trailer. I put a B&M shift kit in my 73 Challenger back in the day and it shifted firm and would bark the tires into second anytime you wanted. Mike
