I know just a tinny little bit.
Why I said that was because when the 327 got designed it was made with a 4-inch bore that readily accepted big-valve heads, combined with the relatively short 3.25-inch stroke. With standard small-block 5.7-inch rods, the combo yielded a 1.75:1 rod/stroke ratio, very close to the 1.80-1.85:1 ratio considered by many professional engine builders as optimum for an acceleration engine. Unlike with the later, longer-stroke small-blocks, installing longer aftermarket rods does not severely compromise piston design.
Even compared to the 67-69 Z/28 302. It has the most horsepower per cubic inch of most small blocks.
I just now see that I have no idea what I said, but merely digging through the mush that sits in my head.
