When I looked into this I realised to get the compression right I'd need
pistons as well. The pin size is different on MC and the 20V pistons, so
rods need to go from th 136mm to the 144mm items. On the rods, the
journal size is different and you'd need a crank from the N/A 10V or the
20V engines. This left me with just the block left from the MC.
