Good stuff!
It looks to me like the 302 is the LEAST square of the motors, with the 427 being closer to "square" than the others.
A "square" motor would be like the old Chevy 283, bore and stroke being identical. Some say this makes for the most reliable configuration.
For a motor that "builds rpm quickly" the application generally recognized as "best" has been larger bore relative to stroke. Porshce and many other "race" bred type engines employ this principle. THIS ratio is often WHY a "small block" will generally beat a "big block" in the 1/8th mile, or even 1/4 mile. Or,,,,coming out of a corner on "road course".........
Watch out on the straight away when the big block starts to build some serious horse power and just KEEPS pulling strong!
Based SOLEY on the bore/stroke ratio numbers on the motors I would expect the 429 to "build" rpm faster than the 427.
Now the stroke length on that 460 is downright scary! Theres a motor I would NOT want to spin higher than 6,000 rpm, IF that much!
