On engines that will be well thought of/revered in the future. Past engines include of course SBC, slant 6, Ford flathead 8's, Gen 1 Cummins etc etc... The GM 8/6/4 , Ford 352, Ford 6.4 diesel, Chrysler 2.4 among many others, crapp. I vote for the Pentastar. It will be interesting to see what the legacy is 20 years from now.
