Ok well a crate is a lil different than a vortec from a factory truck
Vortec is a very efficiant head already. A carb can be as efficiant as fuel injection but that's after much tuning which is out of most ppls skill. Even I am having a hard time getting there.

You can do the tbi with all your things but I would suggest getting a custom tune chip to make the most of it.
You can also do a TPI which is better and would create a good combo with the vortec heads. Only downfall is that you need an adapter harness an a vortec tpi base. Which add cost but make a very reliable turn key daily driver.

A carb will be efficiant in one way..cost and simplicity. A holle 650 is a good general carb and user freindly.

I encourage you to do some research and see which one you may prefer. Either way you can't go very wrong.
