What's the difference between a triton 4.6 and a modular 4.6?

I want to get a 2000 ford f-150 with a 4.6 and i have a 2005 lincoln town car also with a 4.6. Both are the 2v engine. Other than the name triton and modular.

Triton is the name used when in a truck,

they're Modular engines
Is that what you wanted to know?
