Another thing is how all the newer engines all run the same almost all the time. I mean with the the electronics if one SRT8 2013 car runs 12.90's almost all of the same model do. Back in the day the et's were all over the place. Car Craft claimed 13.10 @ 107 from a 70 Hemi Cuda but some mags could not get out of the 14's with them as they ran from a best of mid to low 13's to high 14's depending on the tune which was so important back then. I would say the average 1970 Hemi Cuda or Roadrunner ran high 13's to low 14's. But its embarrasing when some person restores one and has it so far out of tune it runs 15's. Put a new Hemi in the 70 Cuda and everyone of them most likey would run high 12's. But hey Hot Rod ran 12.60's in 63 with a 63 Max Wedge car and cheater slicks. Ron
