I've got a CARS magazine from the late 60's showing a Motion 427 converted '67 Chevelle, and I'm sure at least one '66 was converted, as it was just a short block change on a 396 car. The emblems are the easy part, check the casting dates on the block and heads, and anything else that looks like its been on the car a long time. It should all be '66 or '67 stuff if it was done for the original owner. Otherwise its probably just another converted car done sometime in the last 35 years.
