There's a lot of variables to look at to try to hone in on a price. Is the drive-train born with, all the parts there? Is there any paperwork? Do you have a better picture of the cowl tag? How about the gauge package, engine stamping? On original cars there wasn't any chrome on the engine.
You could've received a possible 4 different transmissions with an L72 in a full size Chevrolet car in '66. If you didn't specify you wanted a 4 speed then you would've received a 3 speed on the tree. M20, M21 and M22 were all available. Without paperwork M22's would be difficult to believe since according to Chevrolet documents there were only 2 full size cars that left the factory with one, M21 - 1,595 and M20 - 30,467. I was told the gear ratio of the axle determined which transmission you would've received. I don't recall what the dividing point was, but with 4.10s it probably had an M21. The cowl tag would only tell you if it was wide ratio or close ratio Q for close, W for wide.
