340 4 barrel and 340 6 barrel: were they really UNDERrated?

9.00 x 30 slick were legal by then (I think ) but might have been 7 inch
slicks. I believe 4:88 rear gears and a production A833 four speed. I will
ask Rod in the morning when I see him at the track. Seems like it was somewhere
around 3100 lbs.

The records were published every week back then in National Dragster.
Perhaps someone has kept one from those days and can posted it.
Maybe, the Dragsters are stored on the internet cached somewhere (Not a computer
guy)?
