I may have found my answer on the 288 vs 327 manifolds...

To quote Ross on This Thread:

"Interestingly, although the manifolds all interchange 51-54, the 288, 327, and 359 all had different inside diameters in the runners. I put a 359 4bbl mainfold on a ported and relieved 288 but found it prone to bogging in normal driving because of inadequate velocity in those long runners."
