My '68 has 4.30's, a high-quality 3800 stall lock-up converter, a 2004R Stage 2 overdrive trans from Extreme Automatics, properly adjusted slapper bars and 275/60-15 Nitto Drag Radials powered by a 408" Magnum with EFI and a 250'ish duration roller cam on a 108* LSA with nearly .600 lift.
I've beaten a Hellcat in a drag race, can cruise all day at 70+ mph at 2500 rpm. The car gets 14 mpg around town and 17+ mpg on the freeway at 70mph with the top down and A/C on. It also handles and stops very well. I've yet to have anyone stay with me on twisty roads.
My point is that its all about the combination. Hopefully before summer is over, it will have a 750 hp supercharged 408 with a 4L80 trans installed in it, which should smooth out the cam lope and perk up the performance considerably.
