The fuel system is a single 485 with a jms booster. -8 feed which "y" and. -6 feeds each rail, your feed to return conversion and rails, aeromotive regulator, and ID1700's with 60psi base fuel pressure.
I'm wondering the same thing and going to do some digging. The second engine didn't blow up like the first, I think I caught it before it got bad. I think it's bending rods. It started out you could hear a cylinder down on compression when cranking and had a noise like a rod tick at about 3krpm. By the time I got it back to Dallas, it lost most compression in a cylinder.
I'm not sure about the timing. That would be a question for Rob.
