Tommorow Hoping for the first start of the 360 magnum after rebuild

I thought that too but I don't see it in the instruction sheet. I probably made that assumption since every drawing in the instruction sheet shows it in a vertical orientation. I ran one for years on the street but it was vertical. I guess we will find out.
Ford used those Coils right from the factory on some of their Cleveland powered Mustangs in the early 70s and they were mounted right up front, vertically. They even carried a Ford part number. It just seems like I've seen it somewhere in print. But honestly, I could be imagining it.
