OK, so I have this 79 Ranchero. I thought it was a 351W, but when I went to get a fuel pump for it, the bolt pattern was wrong. so I asked to see the pump for a 351 Modified, and that one is right.
Being a database programmer by day, (back yard car hack on a few weekends a year) I know that computers aren't always on the money, I don't exactly trust the part's store computer.
So.... how do I tell exactly what kind of engine I have?
