I am toying with the idea of replacing the stock "3" coil pack ignition with an MSD distributor and coil. I nearly beleive all the hype and claims about increases in performance realized when a high power ignition is installed. My questions are
1.How does the crank trigger "signal" relate to a cam driven distributor ?
2.Does a "typical" distributor fit under the throttle body inlet pipe ?
3.Does my ACCEL DFI require any specific connection to or removal from any stock coil pack circuitry ?
4.Anybody out there running this type of ignition ?
Jay summed it up well in his response, but I have one more thing to add: when I was at Duttweiler's a year or so ago he was running a Stage motor with a distributor using DFI as the fuel management; the motor had an interface box that went between the distributor and the ECM to mimic the cam sensor signal. I don't know who made it or how much it cost, but it died before the dyno pulls were complete. :-)
This is the same thing I asked a while back and i had no responses to my inquiry, Is anyone using the DIS4 system and how does it perform?

The DIS4 works great. I've spanked out 1400+ HP using this system and put my 3335# regal through the 1320 in 7.85 Sec. @ 176 mph.
Hey KAR thanks for speaking up. I asked back in August about alternative ignit. ... see above 4 questions. Now I have 5th question what is "DIS4" ?
Can you share your set up with me, or at least answer my questions.
