your engine (if original to the car) is a regular 5.0. it is too early a model to be a roller motor which was introduced in the early eighties, and the 5.0 HO is a roller motor with a 351w firing order.
the main way to tell the difference between a regular 5.0 and a 5.0 HO is the firing order. A regular 5.0 will have a firing order of
1-5-4-2-6-3-7-8
