Front Sub-frame Swap

New Guy here. Have a '68 Barracuda notchback, 6 cyl. Have a '77 Valient 4 door, 318 car. Can I swap the entire front sub-frame from '77 to '68 in order to change to V8 and disc brakes? My guess is not but I need confirmation. Thanks in advance, Carl G.

You don't mean Volarie do you?? You can make the steering knuckle fit, but that is about it. You need to back up a couple of years and stick with an "A" body.
