    M90 Gen3 Technical Help....

    Hi Guys,

    Got an M90 from a 3.8 Ford TBird Cougar in the US and looking to fit it onto another application entirely. My questions are:

    1. If it came off the OEM vehicle with discarge facing up, can it be mounted 90 degrees or even 180 degrees to that without oiling issues? I have done Whipples before and had to get new front plates/covers to do this (you have to specify when you order).
    2. Are there different snout lengths available for this M90?
    3. What rib count should I be running if I run this thing pretty hard? I have done Rotrex C38-81 and ended up using 8 ribs to be safe.
    Any help much appreciated!:)

    TIA.

    I have a M90 kit for a inline 4.0L jeep and the snout is about 10 inches long (3x's as long as the T-bird one) and doesn't look like factory Eaton. The sc mounts vertically on the side of the block , at 180*.
