I did my own cam swap with basic tools at my house. I did a lot of research, and took my time to make sure I did it correctly.
I pretty much learned how to work on a car by moding my 02 camaro. I did everything but tune it, and weld in the sub frames. Spend your money on tools, not install fees at a shop. And take the time to teach your self, its worth it.
Also If you plan it correctly you will end up doing the easy mods first and get better with a wrench along the way, so by the time your car is ready for a cam, you will be able to install it your self.
