Found one reference .. Hemmings Motor News ... The data I reported came from an enthusiast magazine ,, doesn’t match what the EPA tested the car at ... http://blog.hemmings.com/index.php/tag/small-block-chevy-v-8/
Seems the bad EPA comparison for power was due to a stuck/sunk carb float ... http://www.carsandracingstuff.com/library/reports/402.pdf so the Car and Driver numbers are probably more accurate. Even with a bad carb issue the car made 10% more mpg and passed 1975 emissions... Chrysler licensed the CVCC technology and incorporated it in that bastardization of the concept in their “lean burn” engines. Ford licensed the tech also but did not use it.
