Hello all, got here by Google search on using the 411 to eliminate the OptiSpark from my 1996 L99/Lt1 Caprice. Since GM no longer makes or sells the Opti and the replacement options are either expensive or not good. If I can make this work out on my Chevy I may try it on my SVO Mustang and on my '68 RoadRunner that still has a carb.

Are you planning to use the EFI Connection LT1 24x system? https://www.eficonnection.com/home/category/engine-hardware/crank-and-cam-signal-kits/efi-24x-product-line/efi-24x-lt1lt4
