We have two trucks we are building in the shop right now that had 350 Chevy engines that never made it out the door. The one in the 49 Studebaker even had the exhaust completed but both owners said to pull the sbc engine and replace it with an LS. The 350 in the 1950 3100 had never been fired up. Also a 70 Blazer, 34 Ford pickup, and 34 Chevy Master 5w coupe are getting LS engines to start with.
