Well yes, yes I do. Thanks for asking. And Bigsapper you are right. I bought a new 69 SS396 4 speed Chevelle back in the day, took it to the track off the showroom floor and ran low15's. After a little tuning and driving technigue got it down to mid 14's. And I thought that was fast;>)
I'm the guy with the highly modified 6.2( pace edwards tanneau cover and bedrug ) that runs 13's and yes, I think under the right conditions all the new 6.2 8 speeds will run the same. My cut off is 98 mph which limits my et also. The reason I say that is my friends 6.2 8 speed yukon denalli was running 14.0's the same night I ran 13.8's and on a cooler day i ran 13.7's which should of put him in the 13's if he would of ran the same day. His is unmodified also.
