CLASS RACER FORUM - View Single Post - how about the class winner from the 73 summernationals

I/SA=12.00 Possibilities, 67 Pontiac

My guesses in likely order:
428/360hp Big wagon
326/285hp Tempest 4dr HT or Convert or FB Convert
400/325hp Catalina 2dr HT
400/333hp Grand Prix

Another question:
In 1971, Fields won D/S=8.50 class with his RamAir2 Bird.
The Ra2 had to be factored to about 375hp to put the car up into D/S=8.50 class.

Now in 1973 Fields won C/S=9.00 class.
Did the Ra2 get factored down or did he switch to a RA1 factored at the GTO's 360hp number?
3300/360=9.17 fits 1973 C/S=9.00 class

I dont know about the 1973 cars, I have no idea how NHRA factored all those Net HP cars back up to "Gross Factored" HP. I have the current class guides online, but who knows what they did back in 1973.

I wish I did - I started running in 1975 so that would be my era, but with all that Net HP factory ratings it has to be a nightmare to figure out what car/engine went in what class for the 1972 & newer cars.
