Ahhh,
Dana, I'm assuming we are talking about the infamous 0-360-A2G with the HA-
rear facing side draft Marvel Schebler carburator, most likely came from a
beech mousekateer with the 47000lb nose gear strut under the sump.
Change the oil sump/carb and intake runners, put on slick mags or XXX elec
ign you will be very close to an -A1A.
I'm guessing you won't fit the original installation around the conventional
RV engine mount ring with the aft sump and carb. The cross bar that ties the
leg sockets is right smack dab in the way.
But if you want a CS prop you may have some problems as most of them were
not drilled for the fitting into the nose case either. But the stock crank
is hollow and will work if someone were to drill/tap this during an overhaul
and the governor pad is there with studs. You will have to put the longer
studs in as well. When you do make sure you seal the crap out of the lower
ones as they are below the oil level with 7 qts and the oil will track out
the threads.
I ended up using proseal after cleaning 47 times with MEK on my 4th attempt
at sealing them. That said, I pity the poor bastard who gets to remove them.
Not sure if anything else is different, I did a parts comparison on this
engine and didn't find anything, but that isn't an absolute. I have one in
my -6 configured to something close to an -A4M as it has a solid crank. (I
got a really good deal on the crank so couldn't pass it up.)

Heyn gang, will an A2G fit a 7, not an A?

Dana,
I installed an O-360-A2G from a Musketeer 'super sport' (yeah right  ,
in my -6 back in 94.
I foolishly had the engine mount modified and had Airflow make a couple
of custom elbows to allow me to mount the Injection under the sump. I
may have some digital pics of this installation, but I DO NOT recommend
what I did.
If I had it to do over again, I would buy a more std A1A type sump and
have a much easier time.
I believe the Lancair folks used to buy the rear carb mount sumps and
modify them, so you may be able to sell the sump.
My A2G did indeed have a hollow crank, plugged to run a fixed prop. I
ran it fixed for 500 hours and then changed to C/S. The fitting that
'W' mentioned as may not be there in fact WAS there on my engine and the
conversion was no problem.
I do suffer from a hard to locate Oil leak, could the issue mentioned
about the lower studs on the governor be my problem? I will certainly
give it a try!!
So swap out that sump and go for it!
