Re: Some more observations

Probably the easiest and cheapest way to convert to EFI is to bolt on a 
Holley Commander throttle-body system.  They go fairly cheap on E-bay.  
That will take care of all your idle and cold-start problems.  No taller 
than a regular carb (might even be shorter).

I'm planning on using an Electromotive system on the 4.9 Rover I'm 
building right now.  The plan is to hook it up to the existing Rover EFI 
hardware.  The cool thing about the Electromotive system is that it 
handles fuel management and spark, so I can get rid of the distributor, 
and you can log the O2 sensor readings while driving, and determine your 
volumetric efficiency from that, and program a correct fuel curve in w/o 
going on a dyno.  Yeah, there's alot more to it than that, but the 
beauty is that you can tell exactly what is going on in your engine by 
looking at the data stream.  Also, if I get a curve that works great for 
a particular configuration of Rover V-8, I can e-mail it to someone else 
who is using the Electromotive system, and they can drive with it.  Or 
if you are having problems, you can e-mail the data to the company, and 
they can help you find the problem.  Tuning your car from you desk!!
Even though I haven't bought the ECU yet, you can download the software 
from the Electromotive site, and play around with it on your PC.  You 
can customize your spark advance w/o ever having to play with springs, 
counterweights or vacuum diaphragms. 
Of course, the user manual probably makes it look alot easier than it is!
Fun stuff.
