When the 327 came out, it was a revelation. Up 'till then, most guys were running 283s, some as big as the 301- but the 327 was a whopping 44 ci (15%) jump in displacement over the 283, and that difference was enough to put the 283 pretty much out of the picture unless you were class racing. The 327 also brought about the big valve heads w/the bore size to take advantage of them.

The size difference between the 350 and 327 was a lot less (~7%) and they both had a 4" bore, so the power difference was nothing like the 327 vs. 283...
