What are all these things? How do they produce power? What is the science behind it? Are they dangerous? If yes, how so?
port
polish
bore (ok, I know what this is)
stroke (this too)
replace cam(shaft?)s
what are LT's?
How pricey is it to do these things? Why do people seem to stick to bolt on's, NO2, and blowers/turbos?
Thanks for the info.

A four stroke internal combustion engine is essentially an air pump. Anything that increases the amount of air passing through that pump has the potential to increase power.
1. Port(ing): enlarging the air passageways in the heads and/or manifold
2. Polish: smoothing the air passageways to help flow more air
3. bore & stroke: determines the displacement (size) of the air pump
4. cams: control the opening and closing of valves which control the flow of air into the air pump. Open them longer or open then wider to increase air flow.
5. LT's: model designation for certain GM small block V-8's.
NO disrespect intended, but if you are interested you might consider taking a basic engine mechanics course at your local community college.

Thanks for the explanations. I have a decent background in physics and a basic (very basic) understanding of a 4 stroke engine, so that all made sense to me (again, on a very basic level).
