The Corvair that plowed through the cinder block wall had two little beer keg looking weights bolted inside the front trunk.

Getting back to the Toros, I was sort of a drag race watcher back then and they loved to stuff two full blown engines, one in front and back for the drags. Like the Hurst Hairy Olds.

They also took Vair and Econoline pickups, turned them around with the cab in the rear and dropped a full blown engine in the pickup box. Whoooeee! They called them backup pickups.
