Paul-

Here are the photos I was referring to earlier.

In the first photo, we see the mounted 13b from the front.  You can  the
the 1-degree tilt to the right issue we'd mentioned a few weeks back.
You can also see (if you look real close) the flex of the SBeam  from the
engine load.  I wonder whether the tilt to the right is the source of
the interference for the VAM.

Photo 2 shows the interference.  Cutting the exhaust tube & increasing
aft tilt will allow it to clear the tube.

Photo 3 was supposed to show the flange not seating - but you can't  see it.

Photo 4 shows the vertical clearance under a cowl for the whole setup.

Photo 5 shows 3 inches of clearance at the top of the redrive mount  plate.

Photo 6 shows 3 inches of clearance at the top of the water pump.

Photo 7 shows the oil pan, since there was some debate on whether  we had
a std or large capacity one.

Photo 8 shows a relatively stock M2 bottom cowling.  Interference  by the
vertical mount tubes prevent a perfect fit.  Not big deal, our bottom
will have to be blockier up front anyway for the shark mouth scoop.

Photo 9 shows things up front looking good.

Photo 10 shows an inteference by the starter motor.  Again no big  deal,
since we can massage our cheeks to not do this.

Photo 11 shows the top fitting nicely.  We have it pulled back because
our length upfront is about 3/4" less than this cowl was made for.
(That's me holding it on btw).

Photo 12 shows the fit working pretty well up front.  Same inteference
by the starter motor.

Photo 13 shows trying to get as close as possible to actual fit.  You
can see the roughly 3/4 pullback at the rear.  Up front the distance
from prop flange to cowling is about right to accomodate the spinner.

Mark,  Thanks for the photos.  All in all, it looks very good to me
particularly the clearance over the engine.  Plenty of room for the
intake if you decide to wrap over the top.  RE: the engine being
rotated to the right, the only thing I can think of is that I was off
one degree when I set up the fixture.   In the fixture, the S-beam is
bolted to a shaft which can be rotated to clock the mount and also
move in and out to set the prop flange to firewall distance.  In
clocking the beam, I have several reference points that must line up.
I have not  had a problem prior to this.      Jerry

Try putting a 1/2 inch spacer behind the top right hard point on the firewall.
