Product Info








1966-1968 Chevy Corvette Big Block Aluminum Performance Radiator. AT/MT Cars. May need to replace with longer drain plug to clear shroud.



These COLD-CASE radiators are Tig welded 100 percent aluminum and absolutely beautiful. Don't buy a 3 or 4 row aluminum radiator! It doesn't cool as good as these oversize 2 row models.
