How do we blend race car and comfort?

Cope, I agree. 90% here advise people to install the 3.91's, rough idle cams, 3800 converters, and when they are done all they have is a quick car that nobody wants to sit in more than 60 seconds. I'll say you can have all the fixn's for your comfort, smooth idle, and still go 12's and still cruise 70 mph on the interstate all day. Build a torque monster with about 350 hp that runs fine on 87 octane, and keep the gears around 2.94. Or 3.55's with OD.

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.
