How to tell if you have a V8 or 6-cylinder Core Support
Note: 1955-57 Chevy’s mounted their radiators in different positions, depending on which engine was installed, V8 or 6-cylinder. The V8 radiator mounted in the V8 position, engine side of the core support, and used a V8 core support. 6-cylinder cars mounted the radiator on the grille side of the core support for clearance, since the 6-cylinder was longer than the V8, and used a 6-cylinder core support. The handy info page to the left will explain things better. Click the pic for a larger version.
