As for odd/even cylinder location, it's a bit tricky to definitively say "odd" or "even" side without seeing the engine directly. Ford's Triton V8s have a somewhat irregular cylinder arrangement. However, generally speaking, cylinders 1, 3, 5, and 7 would be considered on one side (the driver's side in most cases, but double check your specific truck), and 2, 4, 6, and 8 on the other (passenger's side). It's best to physically look at your engine to confirm.
