Bill,
My efforts on the registry have been directed at the LS-6 but since the LS-5 is the same exact car sans the solid lifter engine and tach, I had started to include (seperately) the LS-5 in my records. I would like to expand more on the L78 as well but I have been waiting for any experts on those cars to offer their help as I have not studied them as much.
