I am half-tempted to do a cam swap since I have to replace a set of springs anyway. I need to locate the spark plug hole adapter, but I have the spring compressor lined up. I have never seen stock Z06 springs; do you think the springs in the picture are not stock?

Alright, guys, I am on the fence about this cam swap. My '02 Z06 is all stock and has the broken valve spring listed in this post set. With 85,000 miles, am I crazy to not go ahead with a timing chain and oil pump replacement along with a cam swap? I don't necessarily need more HP, but if people claim that the chain is due to fail, I think I should go ahead and replace it, which leads to the cam/pump swap.
What do you think? Am I looking down the barrel of a loaded gun not going ahead with the chain replacement?

If you are happy with the way the car runs, and feel the HP is adequate......then leave the cam alone. How soon the chain will meet it's demise has a lot to do with how you drive the car. There is a huge difference between a street driven car, and one that does auto-xing. If you want a piece of mind, and more HP is not your goal, change out the pump, chain, and springs.....and enjoy your car.

Chiefsr, if it were my car, I would go ahead and replace the valve springs then check to see if you have any collateral damage from the break before throwing a bunch of money and time at the engine and then finding you have internal problems. Run the car with the new springs, do a leakdown/compression test and if O.K. then you can start thinking about mods. But if my car with that mileage I would leave it alone. Good luck.
