No, no, no, and no. I got the TBI type system. It's got a 4 injector pod above the intake manifold. No modification necessary. Just squirts fuel down into the manifold. Not as efficient as a multi-port injection setup, but at 15mpg from a 390, I wont complain. Oh, the intake is a plain old Performer RPM.

No direct injection obviously.

No crank sensor. I'm using a Mallory Unilite distributor. It works fine when you curve it correctly. The Holley fuel injection computer CAN control timing, but I currently dont have it set up to. Once you get the timing curve where you want it, where's the advantage? Sure, if you're going racing every weekend you could change timing a lot easier, but since I'm not...

If you want to go with a real multi-port setup, I suggest you find an Edelbrock Streetmaster 390 intake manifold. It has the ports in line which will make it easier to run injectors.
