13.3's to 11.8's to Forget it...

Do your porting on some 360 castings. You can even use the 1.88 valves if you want.

Strip Dominator.
750 double pumper, not a HOLLEY. I'd do a ProForm before I bought anything with the Holley name on it.
Racer Brown cam, preferably SFT.
Hooker 5204 headers but you need to lose your power steering if you have it.
3.91 or 4.10 gears. I'd want the 4.10's but I like gear. RPM under 7500 doesn't scare me (neither does 9k but I won't spend the time to fix the junk Chrysler oil timing.
Custom PTC torque converter (or a QUALITY brand you like and trust...I only trust PTC and a couple of others and if they don't spec a 4000 stall make them tell you why. 4500 would scare me.

Done.
