    Bought a MoPar 360 2 bolt main race R block.
    The lifter valley doesn't have the usual return drain holes.
    Any one modify these for drain back?

    Is that the one for sale here on FABO?

    Some of those blocks were dry sump only stuff. I *THINK* you can make them wet sump with out too much work.


    I'll look later today and see if I can find my R block paper work and see what it says. Even with a wet sump I wouldn't do anything to the lifter valley. The oil will find its way back.

    The paper work I have seen on these block and the way I have seen them done was to drill drain backs in the valley which seems to work in 9 second mills just fine. Just don’t drill into the cam bearing area! LOL!

      any paper work would be great.
      bought this block from a guy in texas on classracer.com.
      I'm using it for a stocker engine.
