Aftermarket EFI on a Magnum- your experience??

Which system did you use? How did it work out?
Would you do it again?

I was pretty psyched about the Edelbrock Pro Flow 4 but they're not available for our Magnums (LA small blocks only).
I know its more money but install a set of trickflow heads, then you can run the intake. Or see about getting the edelbrock intake drilled for the magnum bolt pattern
