440... Carb or Fuel Injection?

The Holley Sniper is $999 and it comes out of the box with data logger and the ability to control the ignition. It also has the ability to run a digital dash setup, control electric fans, etc. All of that stuff is built in. If you buy a carb and then add all of that stuff you'll end up spending 3x as much money.

And you still need an efi fuel tank for it, fuel pump and distributor. The $999 kits don't have that included.
