That pillarless sedan is the Lil Coffin. Built in the early 60's, I think. It was brought back to life in the last few years. One of the mags did a feature on it in the last couple of years. Do a search for it and you'll probably come up with all the info. Nice color on the motor!
If you're interested, there are three more segments to the vid. Go to youtube.com and search Piston Poppers (Montreal car club) and you should come up with them.
I got a kick out of every one in suits/ties at the awards. That was the early 60's.
