I don't think i will ever understand the MNZ thought process.
they have classic classes but change the capacity to be outside of what was in the rules in those eras.
like allowing GP 250cc 2 stokes in F3 when the periods only allowed 125cc.
For f1 there is no allowance for 4t twins vs 4t 4's so its 1300cc 4's against 1300cc twins when thse era rules were 750cc 4 's vs 1000 twins
