Blake i dont think you can mix these with the ECU i think it throws off the timing curve?? Not 100% sure hopefully somebody with more knowladge will chime in.

I should know more about this swap soon. I am doing the same conversion on the 402 that came out of Bad Penny, we will use the GMPP 48x computer, harness, and gas pedal on it. I have to change reluctor wheel and crank sensor, also change cam sprocket from 2x to 4x. I hear there are 4 different cam sprockets. Goodson makes a reluctor wheel indexing tool, if you get more than 2 deg off in positioning the computer will not function right.

My 60-2 (58x) Crankshaft Target will provide for greater Spark Instant (1/4 degree) resolution.
(Patent expired, less cost, the "dual" element BLACK sensor provided for rising/falling signals)
Many of the GM EMS can be calibrated for that CT.
The BLACK Crank Sensor WILL NOT WORK, you will need a
LS-7 GRAY crankshaft sensor.
What is the position of your camshaft sensor ?
The LS-2 (front cover) camshaft sensor has the
TWO OUTSIDE wires reversed with respect to the LS-1 rear camshaft sensor.

mike norris hepled me out this is the GM # 12586481 for the 4 segment cam gear the uses the 3 bolt mounting and the front cam pick up.
i changed the reluctor and pick up (grey Pick up fro 58 tooth)
i am also using the GMPP comp harness and fly by wire gas pedal.
i also ordered the HP tunner software to help tune the comp, turn off the knock sensors ( the iron block does not have the same mounting location , i was told that the knock sensors are esentially tuned microphones and changing them from an aluminum block to an iron block would probably cause problems anyway.
yea all this stuff just bolts together????? sure it does
I realize the original question may not be relevant any more, however in the spirit of completeness the 58x wheel is all in a single row. It will not need to be stacked like the 24x.
Lingenfelter makes a conversion box that allows you to mix and match the 24X with the 58X. They may be able to custom program something for you if necessary.
