What was the ultimate "normal production" factory A Body?

Absolutely Pure Stock?
I'm torn between a 71 340 because of the big TQ, hi-compression, 2.02 heads, etc. 340's love big carbs.
Or my favorite, a 68 Barracuda strippo notchback, big cam 340, 4 speed w/ 3.91 factory gears. I'll bet with the right driver (Hello Ronnie) it may have been good for 14.0's.
The 69 M codes have the potential to be in there too but running all these cars on the stock E70 X14's it may lose.
How 'bout a "D" dart though that has to be considered a drag package.

There was a F.A.S.T. car at the nats this year, a 383 cuda that was in the 12's. But how "stock" was it? Nobody says what they have in those things.
