Hey Marvin==It has just one that is in the middle of the block. GoodluckJoe

The 4.6 in the Marquis is a Single-Overhead Cam design, so that means one cam in each head, for a total of 2. (The older, 5.0 liter V-8 had one cam in the block; perhaps that was what the first respondent was thinking of.)

All "Aero" Marq's (1992-2009 model years) have single overhead cams (SOHC), which means the single cam is on the top end of the cylinder heads, one on each side of the engine block. This applies to the two valve and three valve engines.

However, there is an optional dual overhead cam (DOHC) engine that was available in the Mercury Marauder. The DOHC engine has two cams on top of each cylinder head for a total of four. This applies to the four valve engines only.

The "Box" (pre 1992 model year) Marq's have overhead valve (OHV) engines, and have a single cam located under the intake manifold, in the engine block, and directly above the crankshaft.

It is a Mercury and Mercury is a division of the Ford Motor Company so...technically it is a Ford.
