    It would be extremely odd for an 1980 Car to have an 8.2. It was discontinued back in 72 Yes some of the bigger cars got the 7.5 as early as 77. And pretty common by 1981 in caprice, olds regency/delta , Electra lesaber. But it looks like an 8.5.
    7.5 does not have the side c shape in cover.

    It's a big car 8.5, not the same as a g body 8.5 from a GN, if you were wondering.

    Hey every one been awhile, i still have the Buick been working on it little by little and i just wanted to run down all the minor things ive got done some are things u guys told some not so much.

    First i placed every vacuum line and hose that did not meet my standards so i would said 87% percent of them
    Next almost the whole brake system as well
    Next i clean the carb. And put a new fuel filter in because it wouldnt stop stalling
    Then i purchased the re curve kit and didnt put it in lol
    I gave it an oil change and switched it to 10w30 synth blend
    Next is the ac system before summer comes around along with the rest of the vaccum lines but i messed up what looks to be a TVS "Thermal vacuum switch" and man is that part hard to fine let alone get the correct name.

    Make sure the oil your using has a decent level of zzdp/zinc additive or get some addictive like cam break in additive, or stp . Im not aware of lucas additive having higher levels of zinc but it may.

    You need zinc for flat tappet lifters. Roller lifters do not need it.

    Your engine needs zinc. Next oil change or asap drain that oil and find a quality NON SYNTHETIC oil and add zinc. Flat tappet engines need it to promote the longevity of the valvetrain. Use a good filter too. Whatever the parts store book reccomends for your car as a factory replacement. I use AC Delco or Bosch, whatever one I happen to walk by first. I have the Bosch 3423 on my car now.
    If you can find it, my local napa is the only one near me that carries it, Valvoline VR1 comes in a 10w30. It has zinc premixed in. Thats what I run. Diesel oil doesnt have as much zinc as it used to but some people use that. Dont run thicker (higher number) oil than 10w30, especially when cold. It will stress the pump. Imagine trying to pump cold maple syrup vs warm. Warm is 10w30, cold is 20w50.
