'Match Race' ~ 1968 Barracuda '340-S' vs. 1971 'Duster 340'

Seeing the cam options these are both 4 spd. and yes they were both available with 391's. I had both but the 68 was a dart. The 71 would pull on the top like a freight train. I would like to see the actual numbers from back then on this match up.
