    windage tray

    I needed to cut about an inch off of my oil pan to clear steering on my 65 impala project.

    My question is...should I cut an inch off of the windage tray also or just eliminate it? Car will be a daily driver and I do not plan on racing it.

    There is some sort of round thing that goes around the suction tube for the oil pump that would also need to be trimmed.

    I have a plasma cutter so trimming will be easy. Just weighing the options. The two bolt holes on the side with the round housing are gone from the pan already.


    Any suggestions appreciated.

    If you run without it you might be looking at a 10hp loss up in the higher rpms from oil slosh. If you can just trim it and leave it in that's what I would do...but on my 408 build I would have had to shim mine and do some grinding on the inside of the pan to get it to fit with the longer stroke crank, so I left it off on mine.

    We need some updated build pics on that thing!

    I forgot to mention that I am talking about the part that bolts to the tray and not the one to the engine. I think it has something to do with the oil being deflected to the bottom of the suction tube.

    Ok, so your talking about the piece that bolts down in the pan and covers the sump?

    Do not quote me on this, but I think I would trim and use it, I "think" that piece keeps the oil down in the sump to be sure you don't thrown all the oil to the back of the pan, suck strait air and starve the motor of oil
