Pete,
In this article Hot Rod Magazine states "Chevy 383s destroy 350s in overall power".
http://www.hotrod.com/articles/hrdp-0503-chevy-383-engine/That is hardly news and HRM details out how to do that very popular engine build. Over the decades the various enthusiast publications have had different versions of that same article on how the a 383 makes 40-50 more horsepower and foot pounds of torque that a 350. If nothing else those articles are interesting reading.
