    I've got a 12V71TT that I removed from service on a genset. It currently is set at 580 hp @ 1800 rpm with twin turbochargers, and adaptable exhaust manifolds that I could turn around for truck use. My question is this, I'm wanting to install this into some sort of Mack chassis but I have no experience with diesel trucks other than a B model, so what chassis will allow enough clearance, and allow a large enough radiator for cooling? I plan to show and haul my B61 tandem tractor, and my AB dump most of the time, but the truck probably will not get much more use than this. I know this engine well as I had maintained it the last 20 years it was in service at work and it is sound. What do you think of an RTO 910 transmission behind this engine? I have one that I rebuilt a couple years ago and tested in a B61 (replaced with a triplex), awaiting some destination.
    Hope I don't annoy anyone with the questions as I've probably asked some of the same ones in the past but can't remember. Funny how the mind slows with age.

    The 12V71 was available in RL/RS700's and FL/FS700's,model code was 771,example,RS771LST.Don't know about the fit of the twin turbo's though.I think I would go a little heavier duty than a 910 tranny,at least a 12513,14613 would probably be best.

    We had a similar genset engine here that ended up repowering a KW that had a 12v71 originaly, the blowers didnt present any real problems, it would have looked cool, with the exhaust pipes exiting the side panels though.
