This 1963 Plymouth Valiant,is powered by a 2500hp V8 blower.
It has a 528 ci engine block and stage 5 heads,that are the only water cooled heads to run a ¼ mile in 4 seconds.The spark plug holes are relocated to the opposite side of the valves.This complies to NHRA plug and front spindle rule and allows a weight distribution,further towards rear tires,which means the motor can be moved further back.This engine assembly is a fairytale on its own,we advise you to watch it.
