Hot Rod did a comparison of 60's small blocks in the Jan 2010 issue. They configured the engines as closely as possible to the originals, and ran them on a modern dyno with dyno headers and the same holley carburetor. They did not test a 427FE, but the numbers are interesting.

Shelby 289 - rated 306HP, tested 302HP
L76 327 - rated 365HP, tested 356HP
Boss 302 - rated 290HP, tested 372HP
69 DZ302 - rated 290HP, tested 356HP
70 LT1 (350) - rated 370HP, tested 353HP
70 351C Cobra Jet - rated 300HP, tested 365HP
71 LT1 (350) - rated 330HP, tested 359HP
