In geared 375 hp continentals, rapid power reduction = death. Gear boxes will not tolerate being driven backwards and engines need to be ROP with easy power reductions due to marked inability to match fuel flow to air cooling flow (despite lots of aftermarket injector money spent).
Stark contrast to c340/335 which will run sub 300 cht at all times lop at about 13 gph w/o much shock cooling regardless of experience of pilots with GAMIs.
But by all means, at about $75k for a frem of a GTSIO 520, do what you want. (Not that I have any personal checkbook damage In this regard...)
