Fast is relative, Hemi vs. Hemi

DFX 340 Duster said

Well, bench racing is just that, bench racing. It’s all imagined theory. The proof is in the running. What we need is two different Hemi Daytonas, one auto and one manual, to get out on the highway and do maximum speed runs. I would do it today but I don’t have a Hemi Daytona or Hemi Superbird.

No idea what its top speed was, but Dad tried racing his 440-powered 62 Dodge convertible against a Daytona or Superbird on I-16 just south of Macon, GA, from about 110 mph on up. He got smoked pretty badly, but that 62 was probably one of the more un-aerodynamic cars ever made, at least in modern times.

I remember an old Studebaker ad from 1963, which compared the tops speeds of two factory supercharged Studes - one a Lark, the other a Hawk. The Lark was timed at 132, the Hawk at 140. Same motor in both. Difference in top speed was strictly aero.
