Nicks Garage 383 build

I believe it did 13s with the RA4 cam, showroom stock, the only production 'muscle' car to do so in 1973-4.
Horse feathers. Not without slicks, not without something better than the bullcrappy 3.42 gear, not without headers and even then maybe not. What you been smokin? Those cars weighed 3750 pounds and had 8.5:1 compression AT BEST. No way Jose.
