I had a question about the size of my engine and I wasn't really sure where to post it. I have an 04 4.8L v8. Any idea how big the engine is? Or any idea where I could find out? I know the 7.4L is like a 454, would the 4.8L be like a 290 or something like that? Also, for future reference, would a crate 454 fit in an 04 silverado?
