Re: [Amc-list] EFI on 195.6OHV...

Multipoint injection on siamese port engines is tricky.  It's 
especially bad on fours, though not so much on sixes, because the 
paired cylinders operate 360 degrees out of phase of each other on 
the six.  I'd still run six injectors, or there would be no way to 
balance the fuel supply; the center injectors would have to deliver 
twice as much fuel as the front and back ones in Tom's 
proposal.  Mounting them would be tricky, as would the fuel rail; 
you'd probably have to run a split fuel rail, so that you would have 
room to mount the throttle body.  Angling the injectors to spray 
toward the valves would probably require a thick piece of aluminum 
with the injector mounting bosses milled in.

It could be done, but throttle body injection would certainly be much 
easier.  MegaSquirt would be the ideal controller for either 
scenario, because it is fully programmable with a laptop computer.
