Questions & Answers
Can i change my cam to a stage three without having to change anything else or what should i do?
When you install big bore cylinder kit it's recommended to change your cams as well. Any time you change the displacement of the engine, you should match the valve diameter and cam lift to to the bigger set up if you want to get the most power out of the new set up.
