Do all true 67/68 400 firebirds have 3F on their dataplates?
Why do some 67 400 firebirds have flat hoods with 400 emblems on it? Thought all 400 cars came with the scooped hoods.
Why do some 400 cars have the 400 emblem on the trunk and others do not?
How can you tell if a 400 car is NOM. I know at some point in 68, the vin is stamped on the block...other then that, is it only a guess based on the car having a pre-car build date stamped engine (ex. engine built or date stamped in 2/67 and car built 4/67?
Any other ways to tell if a car is NOM or a true 400. I know a 400 car will have the extended grill moulding and emblem on the front bumper..anything else.
Any other pointers I should look for when going to look at a car which is claimed to be a real 400 car/NOM.
Thanks in advance-this info not in frequently asked questions.
