66 Barracudas (4) Not mine - Enough to make one good Cuda?

A ‘66 Formula S with 4-speed is cool but the 273 Commando engine seems to have been replaced & the cool pieces (chrome air cleaner & wrinkle valve covers) are missing.
I think $6000 isn’t too high but it’ll be a lot of work dragging them all home then parting out the other two cars.
I would check them out say I’m interested but think the price is too much. Then wait two to for weeks and see if he’s willing the sell them for a lot less.
