Anyone in here ever fit a Cummins QSB6.7 in their m998? I am eyeing a few for sale and wanted to get some opinions on it, if anyone has converted to a QSB. Thanks

It might be difficult:

http://www.dieselhub.com/tech/engine-dimensions.html

The 6.2/6.5 is 30" long, the Cummins is 41.7", the width is 26" vs 28.6" and the height is 26" vs 37.8". From a dimension perspective it isn't going to fit. Next is the weight, the V8 is 750lbs versus the 1150lbs of the Cummins which is a serious uptick in weight.

Bad news all round, but you could consider the 4BT. The height is still an issue, but may not be insurmountable.

There is a member on here that is more active on another site that has done several Cummins swaps into the HMMWV. I can shoot him a text and see if he can send me a few pictures of his work if you want.
