Match Race 1972 ~ 'Road Runner/GTX 440' vs. 'Buick GS 455'

My heart says the GTX but if I was wagering a bet I'd have to place it on the GS..they were highly underrated on torque. I'd feel more comfortable with betting on the GTX if it had a set of 4.10's. My brother had a '71 GTX 4sp. 3.54 and I wasn't impressed with the low end grunt I was expecting . BTW...thats one gorgeous Petty Blue '72 GTX
