LPE offers this LT1 to LS1 coil conversion computer to help eliminate some of the issues related to the optispark distributor. It still uses the optical module in the optispark, but no high voltage is passed through it. This will require some fabrication on mounting the stock LS1 coil brackets to the valve covers as well as getting the plug wires from the coils to the plugs. You can fabricate your own mounting brackets, but you will need to custom fit the plug wires for your application.
Other items needed, and not included: Coils LS2 or LS1, plug wires, coil harness.
LS1 version would require: 8-#12558948 LS1 coils, 2-#12562864 bracket (for coil mounting), 8-#10258914 bolt (or 6x1x20mm equivilent), 8-#12560038 bolt, 1-#10110859 oil cap, 1-#85241 Magnecor wire set (for valve cover mounting) or Taylor cut to fit wires. 6-1/4x1 3/4 pan head bolt/stud (bracket mounting), 2 - LS1 coil harness.
