1963-1964 Cadillac Aluminum Performance Radiator. Use for all 390/429cid applications.<br><br>This is an upgrade with top and bottom tank being 3 inch width. Check bottom bracket on original and if you cannot fit 3 inch you would have modifications to make. While it has OEM stamping, it does not line up with the original layout. This item is meant for those who have room for the wider layout or can modify bottom to accommodate the 3 inch wide tank (worried about thickness, try the 3 row SKU 221015)<br><br>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.<br><br>These radiators are original appearing and have the correct stamping.
