Almost is as good as a mile, a Meteor tank engine is almost a Merlin, however the pistons etc are as a lot of the parts, manufactured differently, I think one is a casting where the other is forged..
It's cuckoo land to think just because there is a marine, pumping or generation version that they are one and the same engine, you do not require the same qualities from a ground based engine. Parts etc can be built from cheaper materials where weight is not a factor etc.
