How much is it and what are you looking to do? Factory intake or aftermarket? Stroker? If you’re doing a build, Eagle heads can be added, although early 5.7 heads can flow a ton of air as well, they’re just at the bottom rung (although the bottom rung is pretty high in this case, they flow 265+ untouched) of the factory offerings

Go for it. The 03-08 5.7 offers the most potential vs. cost other gen III engines IMHO. It is also the most versatile especially if you are thinking of using a carb.

There are Crap, Junk, I'll do you a favor I'll drive from my end of PA to yours to pay you what you paid.... wave

Seriously, depending on what you want to do, it's your best starting point.
350-425 Hp is not that far away from a stock long block, a good crank,rods and pistons, 450 to about 550 is achievable with a set of worked stock heads. Eagle heads can get you to 600 NA.

A early 5.7 based 392 stroker would be killer
So easy to make power

I find the 09 up for half the price or even less than that vs the early ones. I've had 3 03-08s, all ended up with spun rod bearings. I'll never install another 03-08 without pulling and checking every bearing no matter what the mileage or how clean it looks.

What all is required to swap into a 67 Dart that currently has a 340 4 speed in it?

I won't install one with out removing everything factory, its like a 9 inch ford rear, once you remove all the factory stuff , you can really beat on them.

Motor mounts(http://www.engine-swaps.com/Pages/ProductsType/57.61Hemi.html#head6 )or front plate) Headers(TTI) and some form of ignition system, the MSD Hemi-6 seams to be a good one to start with for NA. if your going Fuel injection Megasquirt, or Holley EFI
Your Bell-housing will work , you just need a G3 hemi specific Flywheel.
