The Vin number will tell you what size engine that car was produced with. Go on line and do a google search for old vin search...

Yep - 68 saw the shift to 2 versions of the basic 350; a 4 barrel and a 2 barrel version. Also offered was a 230 CID, in-line 6. Sounds like you already solved your problem if you know it originally had a 350 4 barrel. Putting one back in should not be a problem provided the owner that swapped the original out did not alter the engine mounts.
