Mazda was sold to ford, that is a ford truck. You can go to the library and copy (for some change) the papers from the repair manuals.
The 3.7 liter V6 that Ford started using in the 2011 Ford F-150 has ( 1 ) long timing CHAIN from the crankshaft that goes to each cylinder head and in each cylinder head there is a short chain that connects the two camshafts for the twin independant variable cam timing
500 rpm
It is a twin overhead cam engine that uses 2 chains. It's a Mazda engine but Ford used chains while for Mazda cars they use belts.
Your engine is a twin cam.

The Suzuki GS1000 is a vintage motorcycle. They are a line of Suzuki motorcycles. They have air-cooled parallel-twin. They also have inline four engines with two or four valves for each cylinder.
The term 'big twin' is almost always used to refer to V twin engines, such as the Harley Davidson which were, for a while, the largest capacity motors on the market until about the mid 60's when the Japanese manufacturers started turning out 1000cc four cylinder engines. newtest3
