The cost of camming a V6 Mustang can vary depending on the specific vehicle and what type of modifications are being made. Generally speaking, aftermarket cams can range in price from around $200 to over $1,000. More extensive mods like porting and polishing work can add even more to the total bill. When it comes to installation, many DIYers opt to tackle the job themselves in order to save money. However, for those who aren't comfortable working on their cars, it's always best to leave this kind of work to a professional mechanic.
