GM/Chevrolet are still making small-block 350 engines, they started in the 1950's https://www.gmperformancemotor.com/parts/19433032.html

I have a feeling GM is going to keep making pushrod v8's until the eventual death of the internal combustion engine.

This comment made me question the specifics of my mental model pushrod vs overhead cam engine. I found this site that has three nice gif’s which was exactly what my visual brain wanted to see for comparing the differences - https://www.samarins.com/glossary/dohc.html

Thanks for the comment as it was the impetus for me to expand my engine knowledge today!

I’ve noticed Honda puts an emphasis on reducing stress. I have a 20 year old Honda which still runs fine because everything about it seems “overbuilt” - other owners say it runs fine without coolant, oil, etc - just keeps plugging along.

Someone will, because it's a useful form factor. And that someone is gonna be the people who are the experts in it, which is pretty strongly arguably GM. There have been sooooo many SBCs shat out into the world in industrial applications that even if GM stops making them someone will keep making them.

They were, at least.

Massive recall on the 6.2L versions of their V8 engines right now.

Um, no. Go ahead dump your oil and coolant, go drive your car, and report back how "fine" it did.

(No, please don't actually do this. Although here's a guy who did, for the clicks. The Honda did impressively well, but it wasn't "fine". https://www.youtube.com/watch?v=zyejT4VPzlE)

Toyota 5A was in production 1987–2006, and IIRC was licensed to Chinese manufacturers afterwards. The A series as a whole lasted 1978–2006. Less modern than Honda K, but these were lovely engines. They just won't fail as long as you replace parts on time.

This is called lying. They are lying.

Coolant sure, my RSX has a radiator leak for the past 2 years.

Oil not so much.

A lot of bigger engines are running right on the edge of oiling problems these days. With fuel economy rules being what they are it's just how it is. GM isn't special in this regard. Ford is killing a lot of cams and lifters (a problem GM fought through some years ago).

Meanwhile Toyota[1] is recalling blown up turbo v6s left and right (for problems that you can't just dump different oil in to solve) because they didn't invest in keeping a big v8 on the cutting like GM did and they didn't invest in making small turbo stuff last long like Ford did.

[1]Mentioned not because they have unique problems but because who if not a Toyota fanboy makes a comment like yours
