I'm currently performing a "test fit" of the Warp 11" motor in my 1993
Toyota pickup. I tried lowering the bell housing into its original
location: BIG PROBLEM! The CE bottom of the 11" motor hits the steering
linkage...

Would it be a big deal to have the top of the bell housing 1" higher than
it originally was? Should I raise the rear end of the transmission by 1"
also?

Everything turned smoothly by hand and with a 12V battery charger running
the motor. My charger did overheat a little earlier than with just the
motor attached.

I remember when I helped a friend put a Ford rearend
in our 1965 Mercedes that he said that we had to have
the angle of the motor/tranny face the same as that of
the differential. This is because u-joints are not
constant velocity joints. The driveline will actually
speed up and slow down while it turns but the drive
shaft from the tranny and the input shaft of the
differential will remain at a constant speed. Given
that, I would say that you should raise both ends of
the tranny the same amount to keep its angle the same.

Yes, you can raise the motor, but you must also raise the transmission so
the motor and transmission is parallel to the differential. Moving up 1
inch and if the drive line is 6 feet long, than this will pull out the
transmission yoke about 1/4 inch more, which should be ok.

Lower it is the big problem, because you could bottom out the drive line
yoke if the transmission is lower to much. I lower my vehicle 4 inches which
causes the drive shaft to move about 1 inch into the transmission. I had to
move the transmission ahead about 1/2 inch and rise it 1/8 inch on
transmission mount spacers.

The 9" in my '94 is pretty close to that linkage so I understand what you're looking at. If you raise the motor 1" (I think you can) I'd raise the tranny a bit (looks pretty straightforward) but not as much as Roland suggests. Driveshaft movement into the tranny is an issue but you also want to minimize any change in driveshaft angle as someone else mentioned. The two issues seem to be related but I think the problem can be resolved.

Let me know if a picture of my installation can help.

How far off is the front of your transmission? The only reference to how
accurate this alignment should be comes from a company selling alignment
kits (http://www.jagsthatrun.com/Pages/Parts_S10-DrvshftKit-Short.html)
They mention 3 degrees as a maximum mismatch - and that it gets worse when
carrying heavy cargo.

No transfer case, it's a vanilla 2WD, 4cyl w/manual steering. On the plus
side, the odometer works with the ECU disconnected. Can't spin the motor
fast enough to know if the speedo still works too...

A 1" tranny lift should be OK. It should still leave 1/2" to the bottom of
the truck floor. A picture of your setup would be great!

Roland's warning was that correcting the tranny/diff alignment may cause
the driveshaft to shove too far into the transmission. This can happen if
the transmission (or suspension) is lowered. In my case, raising the
tranny *increases* this distance, so I have to make sure the driveshaft
still has enough "bite" on the transmission output shaft.

Big thanks to everyone for all of your help and advice!

-Adrian
