Newer vs Older

As to which is better IDK.
I have had a 65,a 69,a77, and an 80hydro; mostly stock slugs.
>The 65 was an oil-burning POS from day-one. I didn't have it long before I replaced it with a JY340. I bought that car in~73, so that slanty was 8 when I got it.
>The 69 was tired but ok when I got it in 75, I replaced with a store-bought unknown year remanufactured engine, about 3 years later.I sold it to a kid, car and all, after I drove it for about 2/3 Years. About 3 months later, I seen the kid, walking again. Seems the engine lost it's oil and it threw a rod. No he didn't blame me,lol. I think up to that time, he had wrecked every engine in every car he had had; three IIRC. Nice kid.
>The 77, I had custom built with more compression, and a slightly bigger SOLID cam, plus the SS setup.This 77 was rebuilt in 94, and still fires right up and burns no oil. I'm pretty sure it has over a quarter of a million miles on it. Still on the original chain and all-steel gears I think, as I don't recall ever replacing it. Hmmmmmmmmmmm, that's pretty good EH?
>The 80 didn't last long for me, the PO ran it pretty hard.
They were all "good".
