[Diy_efi] Strange EFI

I have not been very happy with the throttle response of a 
single stage throttle body on an engine over 400 cu in.  Its 
just too tricky to avoid spinning the tires every time you start 
off.  I know some have come up with a cam on the linkage 
to vary the rate of rotation to throttle movement.  

I have been thinking about using a stripped Q-Jet to get its 
nice progressive linkage response.  And everything already 
fits my cars; linkage, intake, air cleaner.  Just add some 
port injectors.  But wait!  If a Q-Jet is bolted up there, and 
the EFI quits, I could just hook up the fuel line and I have 
a carb back up system!  Maybe need to drop in a different 
distributor base, carry that with the fuel line.  The carb fuel 
linesand pump are already there, a booster/reservoir up 
front could supply injectors from the same pump.
