Just match your crank to your rods and pistons, then you can put that rotating assembly into any H&F series block. In the H&F Series world, since the deck height is the same for all H&F series it means that you can swap rotating assemblies easily. Why does this matter? Unlike B-series engines, which all have different deck heights and means they must use different length rods whether you're building a B16, B18a or B18c. Or F22 parts in an F23. You get the idea.
If all H&F series engines have the same deck height, what does that mean? That means that you can put F23 parts in an H22.
