OK, so I did the search thing , but could not find an answer.
So here's the question.

I've heard their are differnces between the cams in the that go in the different models that use the LC8 engine ( SD, SM, ADV, & SE ), also their may be differences between different years and between the engine size ( 990 & 950 ) .

So if their are differences, what else is also changed, pistons, heads, valves, and ??.

I'm just curious about the differences
