I got second hand cams , guy told there are stage 2 , i know him i and know how your car ran with these cams , but i want to install them in my car and reprogram , but i don't know how define the Cam spec... do any one of you know it ??
It might help if you included who made the cams and any part number stamped on the units.
It might also help if you included the model year and engine type of your car. It's better to not make assumptions. This can also avoids things like attempting to use a PI cam in a non-PI head.
