Re: curious about sfi



will it work well for large injectors at idle(40.7#@39psi) on a 350/350 overcammed.( my curiosity may be getting the better of me). not sure yet if emissions are an issue..kinda depends on how it gets titled.
I understand that above 3000rpm I wouldn't be able to tell the difference between sfi and batch. If however the circuitry is relatively inexpensive..why not? I believe the caddy(olds) distibutor would be fairly easy to adapt a cranksensor to(it has an extra 'speed' sensor location).

Might work for idle, but how are you going to hande 80% duty cycles. 
Other then for large injectors at idle, and some min emission stuff, why bother (asked rhetorically, been covered before)?.

this may be dangerous thinking but;
since I will probably need to install an injector driver anyway
 
would it be possible using the pulse from the '727 injector driver circuit in the ECM to control a 'black box' SFI injector circuit synched using a crank sensor. I had read that the old volkswagon FI was static at 15deg B4 the intake opening. what I am curious about is "multiplexing?" the pulse from the existing driver and "synching" it with the crankshaft sensor. would some of the DIS circuitry be able to do this?
anybody out there been dere,done dat?
