    Having trouble figuring out what to do with the air intake. Was going to use the filter housing from an M54, but I need to shorten it by 6-8" for this application and then it'll only fit an M35 air filter, which defeats the whole purpose. The box will flow more but the filter still doesn't.
    It is impossible to find a CFM requirement for the 5.9 from Cummins, but I'm seeing reports of around 900 cfm under heavy load, so the original filter isn't enough. Not sure what to do. I may have to shorten the M54 box and fit an aftermarket filter of some kind.

    On my intake I am going with the 8.3 size and intake mushroom, On a side note the first mod they ever did on the 12V was increase the the air filter size.

    Is it just me or does the Cummins sound very very similar to an LDS-465? Both at idle and when revved?

    F yeah! Love the RRAD style driver's seat Good call on engine stop precaution of leaving it in low range. But with the no idle, all was safe.

    Yes, the LDS and 6BT do sound similar, they are both inline sixes, overhead valve diesels with the same firing order. Even a minimally muffled Ford 300 sounds similar.

    I think the throaty attributes of the 4" exhaust is what makes it sound so much like the multifuel. It does have a noticeable whistle too.
