The C1 Corvette was produced from 1953-62 and did not have side engine mounts but rather a front mounting plate. This chassis will require modifications and welding in side mounts to the frame. LS Engines are wider than SBC GEN 1's which leads to crowding the brake booster. It is reccomended to look at relocating the coil packs. 

Engine Mounts-
