McMaster, unfortunately we have to forget about the power output of the 80s cars as the fuel-flow is going to be severely restricted so they can pump as much air as they like in to the cylinders but only so much fuel, expect the amount of fuel available to be about what is needed for 5-600 hp today to get that fuel savings.

@PM not because of the rpm limit but because so much of the engine is standardised ie. it will be a 90 degree V6, 2 intake and 2 exhaust valves, bore will be 80mm. and therefore stroke will be X for all, except for Al.alloy pistons the rotating assembly will be all iron based, the exhaust will be outboard of each bank, inlet will be inboard, etc etc. So the only real differences will come down to the reinforcement of the block casting and the shape and volume of the combustion chamber. One interesting restriction reflects the concern regarding “sounding right” ie. full fuel flow cannot be used below 10,500 rpm. meaning that an engine will not be allowed to develop maximum torque,let alone max power below that rpm, so on the one hand the FIA want engines to last longer but on the other hand they want the engines to be high reving to “sound right”
