1. Yes you can add a cam without changing anything else. I ran an aftermarket cam with stock heads, intake, etc. for quite a while. Just make sure you don't get a cam that's too big (lift in the upper 500's). You don't want to have piston to valve clearance problems.

2. No, you don't need to get an adjustable fuel pressure regulator unless you want to. Upping the pump to a 190lph was a good choice. With that many miles on the car, you're lucky the stock pump held out this long. You shouldn't really feel a difference in the pumps. The only time you'd feel a difference was if you were running a combo that required more fuel and didn't have a big enough pump to begin with. Then when you put a bigger one in, you'd feel it. The 190 will be fine for almost all modifications you may or may not make in the future with the exception of a power adder. If you were to spray a LOT, then I'd up it to a 255. But other than that you're fine. I run a 190 with ported aluminum heads and upper and lower aftermarket intake with a big cam. It's still plenty of fuel for me.

Hope that helped,
Dave
