With msd distributor, Weiand intake, plug wires, and Street Avenger carb, It's about $4000 shipped to my door.

What are you looking to put this in and what hp level are you looking to achieve? Also, do you plan on running 87 or 92 octane gas?
I'm going to put in in a '32 Bantam altered. I want to run
slower than 9.50. That way I can run Pro or Super Pro or even double enter if I want. It would be nice to be right at 9.50 so that the other Pro cars have the chance to red light first.

If it weighs 1900 lbs (we're not sure on that) 415 hp is 9.67. I know there are alot of variables to consider. Just using it as a guide.
As far as fuel, I want to run pump gas to save on buying racing fuel. So even 92 octane would be fine.
Look at it this way bub...
The motor you're looking at from ATK is most likely meant for a low RPM application, such as a truck motor or street car.
It's not going to be setup with the right tolerances to go racing.
Anything used out of it's designed criteria is bound to fail sooner than later. I think you would be better off, for reliability's sake, to spend a few bucks more and buy a better bullet for your car.
The heads on that motor, if they are indeed the ones pictured, are what are known as the "Peanut" port, because they're so damn small. Hell, you have to give them away to get rid of them...
