Back in seventies all the high tech cylinder heads of today either did not exist or were under development. This engine appears to have an aluminum head, most likely an early Brodix. In short, engines were producing a little over a HP per CID, the good ones a horse and a half. The blower on this engine most likely produced HP on a par with the engines, around two HP per CID.
The main draw back for this car would be tires. Tire technology was not what it is today. If the driver did not have really good throttle control he cold burn up the right rear in a heartbeat even with the tires of today.
Another thing would be fuel. The tank looks to be around thirty three gallons but on a mile track with a blower I bet that did not go far, my guess a gallon a lap.
I remember when Mark and Karl Kinser first fielded a Chrysler engine. They could not get the thing to run. Karl even threatened to fire his own son, Mark, if the car did not start winning. Some background there, Dave Blaney was winning with the Kasey Luna Ford. Smokey Yunick is reported to have said that everybody knew the Ford produced forty more HP than the Chevy but the really bad news was the Chrysler was making 40 more HP than the Ford. Karl detuned the Chrysler and began winning. This car might have had a similar problem, too much power. On the mile maybe not but I would bet it was a mean beast on a half mile or less.
For what they are worth those are my thoughts. With them and a buck and a quarter you can get a McDonald's coffee.
