Hi Lomes,

Did a fair bit of work with a Denning coach, 8V71, 7 speed spicer crashbox and tag axle and it was good for High 30,s l/100 in good going...put it on snow work eg. Mt Hotham expect high 40,s sometimes more.

Did half mil K,s in a Denning decker with 8V92 and it used 50l/100 (2k/ l) everywhere, snow included.

Can't give you fuel figures but if looking at older engines look to see if upgraded to "N" series if I recall. Better performance.

ie 8V71NT

Gee , most of the motor homes/buses I've seen have all been four strokes.   (Ahem...)

Seriously though, nope don't know 'em.
