4-speed bell housing runout

[bandt]

Hi guys,
Question about checking the runout on a small block bell housing. Manual says no more than .004 is acceptable. Corrections can be made with offset dowels. I checked the Brewers website and all there offset dowels say they won't work with stock small block bell housings. Where can I get them if required?
I haven't doe this yet I'm just trying to get things sorted before I start.

Thanks,
Brian

Unless someone has screwed with your stock stuff, it should actually be fine.  If the dowels have wear on them, you replace them. To check the run out, use a dial, with a magnet, install it on the crank register, spin untill you have it centered up, then check on the bell housing hole center. I also believe you can go as much as  .009 for max if I recall. But in most cases, 99% of the time most everyone just installs and has no issues. It's when you have miss mached parts, abused parts, or worn parts that puts you into a dilema. The receptor holes in the bell housing needs to be in good shape is all , along with good dowels.

  don over think it, these were not precision machines from the beginning. checking is great, but unless something is crazy off, it should work fine.

    stock stuff is usually fine it's the aftermarket stuff that's usually a mess. But it never hurts to check!

I checked mine and found the runout was a little high.   Offset pins can be purchased here:
