<VV> Conversion to EFI: Is it really cost effective?

[NicolCS@aol.com]

<snip>Craig, what are the jet sizes in your primary carbs and what is 
altitude 
where you live?  Do you use the same same '67 carb/jet setup on the 
street that won the fuel economy contest?<unsnip>

The primaries are 50s.  I live at 2600 feet.  Yes, I run exactly the same 
carb and jetting as I used in the econorun (which was at more like 1500ft).  Here 
are some more pertinent details:
I run 24" OD tires and a 3.08 axle with an EM 4-speed (for its lower first 
gear).  The engine is a 140, so it has dual (low restriction) exhaust, larger 
valves and exhaust manifolds: all of which contribute to reduced breathing 
losses.  The cam is a 95hp cam, retarded 4 degrees. This is the stock "high torque" 
set-up for a PG140 engine. It has the standard 9:1 (or is it 9.25:1?) 
compression.  This unusual cam puts the peak engine efficiency down into the right 
range for my 3.08 gears.  

During the econorun, I ran 40-45 mph, shut-off on the hills, and ran 40psi in 
the tires.  The 100 mile run had no elevation change beginning to end and 
mild rolling hills.  The magic in the econorun was the 40-45 mph speed.  The 
magic in regular highway cruise is in the cam and gearing.
