I didn't make a mistake.
Yes, the 403 (L80) was an Olds. The shaker decal denoted which motor was in the car. "T/A 6.6" was the Pontiac 400. "6.6 Litre" was the Olds 403. Yes, 76 was the last year for the L75 455. It was originally slated to be axed at the end of 1974. It should be noted that the hp #'s that Deathdealer made fun of were the new Net ratings (not Gross) and all of the motors were producing 300-325 ft/lbs at only 7.6-8.1:1 compression ratios.
