I recently found a oil sump from a 200 HP IO 360 which I understand was used
on a helicopter.  The advantage is it has a plenum in the sump which
eliminates the 90 degree elbow.  It has been modified to move the injection
servo to the front from the rear which raises the location of the inlet. 
This sump is about 1.5 inches shallower than the stock O 360 and it has
cheeks that are 2.75 inches wider than the gasket line on each side of the
sump.  My concerns are the intake runners and exhaust system.  I don't mind
fabricating the runners but I don't want to end up with more than minor
exhaust system mods.  Has anyone seen one of these sumps on a Lancair?  I
have rough measurements I could use the next time one of my neighbors has
his cowl off but I am expecting the clearances to be so close it will be
hard to tell.         Steve Colwell

PS:  I gave up on Lycon in modifying a O 360 sump for me.  I finally had to
make a trip to Visalia after a year of promises to get my money back.
