Allowed in Appendix K, article 5.8 of appendix VIII if anyone’s interested, which is pretty much lifted from the period Appendix J I believe.
So thus it can be done provided of course that it complies with 3.6.7.1 and is within 5% of the original weight.
Mind you the last time that was ever checked Noah was probably trying to work out what a cubit was........
As has been mentioned before, you only have to look at some of the flywheels and clutches being used today - both of which would be on the relevant homologation form - to figure out that it is unlikely that the crank is actually made to those parameter.
