Okay, so the other day I was watching NASCAR with my buddy, and we got into this whole debate about the engines. Like, how big are those things, really? I mean, they sound massive, and the cars go insanely fast, so I knew they had to be packing some serious power, but I had no clue about the actual size.
So, I grabbed my phone and started digging. First, I just did a basic search, you know, “NASCAR engine size.” Boom. Right there, top result. Turns out, I learned that they’re all running 358 cubic inch V8 engines. Which, okay, cool, numbers… but what does that really mean?

I kept scrolling, and it started mentioning stuff like “5.9 liters.” That I could kind of picture. It’s bigger, that makes sense.
Then, I really wanted to understand the power. The initial results mentioned that they had “approximately 670 horsepower”. That is so much insane power!
I dug a little deeper on some forums and fan sites. Those guys REALLY know their stuff. I found out that these engines aren’t just big, they’re, like, totally custom-built for racing. Everything is designed to push the limits, but they also have all these strict rules they have to follow. It’s a real balancing act between all-out power and staying within the regulations.
So I put the phone down, then I told to my buddy: These NASCAR engines are 358 cubic inch (5.9 liter) V8, around 670 horsepower, totally custom-built beasts.
