How to tell the size of an engine

Hey, me and my friend were talking about engine size in his dad's truck and he was told by this guy that it was a 350 small block chevy (1989) and he knew by looking at the spark plugs. Well i was told its not possible so i was wondering what ways you can tell if it is a 350 or if it's something else (ie. by using intake, valves, headers, etc.). Any help would be useful. Also would you be able to find out by using the internet to run the block number? Thanx.

Lots of experienced people can tell just by the general shape of an engine, more-so the older engines than the newer ones. Since now they stamp "2.2L" right on the plenum, so there's no need to memorize it. On older carburated vehicles they used to stamp it on the filter housing, but once that got dirty/changed for a higher flow housing, that was gone, and they only way to tell was if you knew what the engine itself looked like. Also, the 350 is an extremely common motor to say the least.

Chevy small blocks look dimensionally the same, and to claim that you can tell what engine it is by the plugs is absurd. A 305 and a 350 dressed the same will be identical looking, so he is at best, guessing. Small blocks VS. big blocks on the other hand are easy to tell apart.

You could always take it apart and measure the volume of each combustion chamber. That always works best.. Who knows it might not be a 350, it could bea 349.201.

Measuring the volume of the combustion chamber wouldn't tell you dick, if you wen't by the combustion chamber each vehicle would be about (made up number) 10cc's per cyl.

Hmm so if 1cc = 0.0610 cubic inches(1cubic inch = 16.38cc), using your logic the engine would really be 4.88189 cubic inches? Even for a made up number you're still off by about 345 cubic inches, and I suppose GM just wanted to pull the number 350 out of their asses. Or maybe if he used one of those big ass needle thingamajigys that measure volume and came out to oh say 712.5mL per cylinder, multiply that by 8 wich gives us 5700mL or 5.7L wich roughly converts to 1L = 61.02 cubich inches. Multiply 5.7L by 61.02 and what do yah know we get 347.81 cubic inches of displacement. More commonly known as a 350 motor. N hey what do you know? My fathers Camaro has 5.7L of displacement and it has 350 motor in it.

Whos the dick now? That'd be you.

How can you even talk about an engine when you can't even tell the difference from a combustion chamber and cylinder. Oh smart one? That's right, you're in reality a retard. Yes, I'm tired of your idiocy and cockyness.

Who's the retard now? That'd be you.

Not to mention you can't just measure the cylinder bore/length to determine displacement, it doesn't work like that, but of course you're so smart and realize that they don't just make up an engine and measure it and bam,
"houston, we have 6999cc's of displacement", there's a few more factors that determine displacement.

You can post when you know what you're talking about. Otherwise, shut up because we're all tired of your arrogance.

Haha you can't be serious. The combustion chamber is where the combustion takes place. Thats why they call it a combustion chamber. Some people would also refer to it as the engines cylinders(Just in case you don't know the cylinders are where the combustion takes place). Now is it me that can't tell the difference or is it you? Are you that obtuse or are you playing with me to make yourself sound smart?

No one said anything about cylinder bore or stroke(the proper term is stroke not lenght). But hey since you mentioned it, it is in fact possible to find the displacement from the bore and stroke. For example my V8 engine has a 4.000 bore and a 3.48 stroke. Together the equal 349.847 cubic inches(5731cc's) more commonly known as the 350. My Mitsubishi 4G63T has 2.0L ofs displacement. If I were to fill all of the 4 cylinders up with water they would all hold .5L of water.

But since you're so smart and know how engine displacement is figured out how about you enlighten us with your overwhelming years of knowledge. Mr. I work for Chrysler. And taking out their trash does'nt mean you know any and everything about what they do, but none the less I'll give you a few minutes to thumb through to your "mind" and find out exactly how it is that you can find engine displacement. There are many ways so I'd suggest you get cracking. I'll be waiting....

By not responding you accept that you are infact wrong and that I was correct.

To convert engine displacement (litre) to cubic inch just multiply by 61. For example 2.0L is 122 cubic inch
