I am not having any luck finding a direct replacement OEM type radiator for my Biscayne. I am finding lots of pricey aluminum ones but I don't NEED all that I just want to put in a big block radiator so when I install the big block enginer i don't have to do it again :2_thumbs_up_-_anima
I found this: http://www.radiator.com/radiator/chevrolet-biscayne-1968-price.html?carengine=5.0L,+307ci,+V-8 Exactly which engine are you planning to install? Here's a link for a radiator to go with the 427: http://www.radiator.com/radiator/chevrolet-impala-1968-price.html?carengine=7.0L,+427ci,+V-8
Make sure you get the plastic shroud that goes with it as well. They are available aftermarket if you can't find a used one: http://www.ebay.com/itm/67-68-IMPAL...t=Vintage_Car_Truck_Parts_Accessories&vxp=mtr You will also need to run the thin radiator spacer between the rad core support and the radiator Thin: http://www.ebay.com/itm/1965-66-Bel...t=Vintage_Car_Truck_Parts_Accessories&vxp=mtr Thick: http://www.ebay.com/itm/1965-1966-B...t=Vintage_Car_Truck_Parts_Accessories&vxp=mtr
