Need some Buick expertise

[Guest]

Hi, Could anyone who knows for sure please answer some questions for me. In what specific years was the 455 engine available in the LeSabre line? What was the first year in which HEI was standard on Buicks? What years was the Regal line offered? Was the 455 engine ever offered in the Regal line?

The 455 was offered in Century/Regal line in 73-74 only. In 75-76 it was available only in full size cars.
