I'm a little baffled that the idea of stroke being the determining factor in a engines output is still prevalent. Here's a quick and dirty example of why: both the Buick 455 and Olds 455 are the same size. Buick has a 3.90" stroke, Olds has a 4.25" stroke... Both were torque monsters.The 350 buick came with a very similar 3.85" stroke to the big Buick, why did the Buick make a substantial amount more torque? It was a considerably larger engine.
Let's apply that to our 305/327 SBC's here, which is even fairer comparison because we're talking apples to apples. The stroke doesn't matter, torque and horsepower is going to be determined by the valve train and heads. The place where they occur is determined by the displacement of the engine itself - so long as compression, valve train and port size and shape are identical. The 327 is going to be a better in any situation because it's bigger. That simple.
