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.

john, we're talking about showroom stock cars here man.
