Yes, there you go. The 440 Super Commando crate looks like an excellent choice. It's lightweight, megapowerul, AND efficient; it has it all. I'd switch out that low hanging drag race pan for a Milodon road race pan though.
Cast iron manifolds? Six pack setup? That is NOT the kind of stuff dreams are made of. Like MoparLeo said, dream big. Go with the best of everything out there. You don't want to be kicking yourself later. If I were you, I wouldn't skimp on anything. I'd go TTI headers or better, not heavy dinosaur manifolds. Fuel injection is the best all-around for gas mileage, power, going around corners, etc. 6pack setups have flaws and even on their best tune, aren't as good as the new Holley single carbs, and not even in the same ballpark as fuel injection. If not road racing, I'd go single carb.
Drivetrain, I'd definitely go Magnum T-56 6 speed overdrive, Moser 8 3/4 rear with whatever gear matches the tire size, trans overdrive, and engine cruise rpm. Unless you want to drag race, then I'd go Dana 60.
17 or 18" tires have the best sizes and performance and allow you to run the bigger better brakes like 13"+rotor size and 4-6piston calipers. Once again, if money is not an issue, go with the best stuff available. I'd say forged 3 piece aluminum wheels (Forgeline) in whatever style/color you want. The new Forgeline Grip series Laguna wheels, now THOSE are dream wheels!
While you're at it, don't forget suspension upgrades like Reilly Motorsports Alterktion front, Streetlynx rear with coilover shocks.
Just my .02 cents,
Joe
