Basic questions ?!

I don’t have much knowledge about what I would like to change with the help of the forum! I didn’t just fall on the head when it comes to cars or something like that, but no us-car profi! I’ve often heard some of the terms that I’ve heard before, but I don’t really know exactly what it is! zb. 350cui (motor), then hemi and so things! I think there are many basic concepts that I would like to know about you, or explain! thank you in advance and I’m happy about many answers!!! here my car bought a c5 and wanted to sell it, but the offers for the next 18 birthdays were: 89trans on gta, v8(what else), and only about 17tmls (that’s all right), my father bought it for the last year, and he wanted to sell it, however, he had the offer of a couple for the gta.
