> environmental laws would be much harder to practically enforce with this as you could run virtually any engine anemic enough to get though the emissions tests lol Changing a cam (or cams) in most engines isn't all that difficult. Even without a camshaft you'll still be heavily limited by the shape and size of the combustion chamber and the geometry of the valves. You simply won't be neutering the engine that much.

Changing a camshaft in a classic car is huge pain that requires specialist equipment for setting the timing etc. and getting it wrong can destroy the engine. It's more than possible in a home setting but most home mechanics I know wouldn't touch them. I'm sure it's a lot more complicated on a modern car.

That's overstating the case quite a bit. There are plenty of engines where you don't need special tools. > I'm sure it's a lot more complicated on a modern car. Wait. You were talking about older engines? Then, no. You're absolutely wrong. Swapping out cams on most older engines is a piece of cake. Pretty much anything without variable valve timing will be super duper easy. Pushrod motors are especially easy. There are some exceptions, of course, like the DeLorean's V6 (the cams slide out of the head so you generally won't have room to pull them out without pulling the head).
