Ed -
There is a lot of difference between those engines on the street in production cars compared to current prepped Stock Eliminator configuration. The 327-275 has almost as much blueprinted compression (11.9 vs 12.2), the same heads, camshaft difference doesn't matter much under current rules, and a much larger carb (Qjet vs 585 Holley). Add to the fact that the original 327-350 intake is not much better than a good Qjet manifold and that the original dome configuration restricts flame travel in the combustion chamber and it is easy to see why there is not much difference in current rated hp.

Evidently GM gave some funny specs for the 275. I know of a couple other engines like that.
