The Merlin has the same power to weight at the DB601.

It actually states 1450 lbs but also 1240hp at 2850rpm @ 10,000ft (two values given for the Merlin XX)
However, the DB601N power is WEP. The equivalent figure for a Merlin XX would be 1485hp at 14lb/3000rpm @ 6000ft and 1490hp at 16lb/3000rpm @ 12500 ft and 1280hp at 3000rpm/12lb @ TO, at least in 1942 but the TO figure is applicable to 1940 as well.
