I've looked through my books and this Forum but have not been able to find the bore spacing for the 4 cylinder 1.5 liter and 2.5 liter FP Climax engines. I think they may have been the same although that seems like a stretch.
I can find valve sizes, bores, strokes, but nothing on the bore spacing other than a note that the 1.5 liter V-8 may have had the same spacing due to tooling constraints.
Thanks, in advance, for the info or a reference where I can find the answer.
