Does a 1995 Ford Taurus have a timing belt or timing chain?

On a 1995 Ford Taurus : Both the 3.0 and 3.8 litre V6 engines have a timing CHAIN. The 3.4L in the Gen2 SHO has a timing belt that must be replaced at 100k miles. The engine pictured above is in a Gen3(96-99) and the cam shafts tend to snap next to the lobes. when I buy one to keep for a while, I pull the cams and have my machinist weld gussets between the shaft and lobes, and balance them.
