977H Engine

Hello guys and gals,

I've found a D333 engine out of a D6B for sale at auction, http://www.auctiontime.com/onlineauc...ltf=attachment (hope that's ok to post here) and am thinking (if the price is right) to buy it as a spare for my 977Hs... Would this engine fit? It does look like it's a bit different as far as accessories go... Just curious...

Thanks.
