  As for plumbing of the oil filter and cooler, what you've

suggested is

standard practice and I think most of us are doing this. Racing Beat

sells

the filter block off plate that you mention. In my case Bruce

Turrentine

machined off the filter mount pad on the rear housing, machined an
interconnecting passage, and blocked off the holes which originally

went to

the oil filter pad. This cleans up the block a little and eliminates

the

need for the Racing Beat block off plate.

That sounds real interesting Mike. Got any pictures?
That would give me a bit more room for my intercooler I think.

Anybody have one of Bruce's engines with this mod? If so do you know
what
Bruce did when he "machined an interconnecting passage"?
Bruce is hard to get in touch with.

Normally all oil out of the cooler goes into the block near the bottom
of the rear end housing and is subject to the pressure regulator located

there and then goes through the filter to the main oil gallery. If the
filter
passage is blocked by this mod the oil needs to get into the main oil
gallery
somehow.

Paul,
I performed this mod on my engine.   I cut the filter mounting pad off
just like your picture - note that sometimes there is not enough
material left to tap and plug the holes.  The trick is to remove the
'pressed in' plug on the bottom of the housing (I think this next to the
rear oil pressure regulator), insert a long drill thru this 'now
accessible' hole and drill/connect the oil passages at the top of the
housing.  If you take a look at the housing and follow the oil passages
this will be readily identified.  Lastly, tap the hole created when you
removed the plug and use a pipe plug to close off the hole.  This mod
bypasses the filter pad and allows oil to flow directly into the main
oil gallery.

Thanks Ken. Here are some pictures of the suggested mod.

BTW Needless to say not something one should do with the engine 
assembled because of chips that would get in the oil galleries.
