Port science has improved tremendously in the past 60 years! Those old articles are pretty much wrong! In 1957 we marveled at a 283 Chevy with fuel injection making 283 horsepower! And a '57 Ford 312 with supercharger making 300 horsepower! Wow! And they ran what, 15 seconds in the quarter? Now little 2.0 four bangers do that and quicker. New aluminum heads for old style engines also up the power significantly with modern port theory and combustion chamber design.
