Hobodog - the engine of the La-7 is the same as the La-5FN, i.e. the ASh-82FN, rated at 1850 hp.
As for the thread topic, I don't see why there should be much difference between the La-5FN and La-7 cockpits. The La-7 is mainly different due to aerodynamic and material changes.
The AH cockpit only has a passing resemblence to its real life counterpart. For instance, neither the La-5FN or La-7 actually hard an artificial horizon.
Personally I'd rather see a few more aircraft added before cockpit's are revisited.
