Very early Big Twin pictures

Ran across these pictures of Dave Brackett and Jim Clark (and a third guy I can't identify) working over Big Twin very early in it's life. It just boggles the mind that Dave built this in 32 days! Look at the frame and bodywork involved alone. For god's sake 2 Sporty engines, auto trans and 45 Servicar rear end. Its just flat amazing. Then throw it all has to come apart for chrome and paint and then it wins the Oakland Roadster show!
