Fender Tag question

No. They are not. Take, for example, 69 model year. H was a 383. Then in 1970, H was a 340. Years make a "little" difference.

For example the fender tag code for a 340 is E55 on the lower left of the fender tag at least 69 forward, if you're not referring to the vin designation.
