Does anyone know the bore spacing on an F54 or N42 block (center of cylinder to center of cylinder)? I assume all the l24/l26/l28 blocks have the same spacing, is this correct?

"For 6 cylinder engines, bore spacing is 3.799" [96.5mm] between cylinders 1-2, 2-3, 4-5 and 5-6, and 3.858" [98mm] between cylinders 3-4."

Thanks! Just what I needed.
