Default 454 radiator

Hi I'm putting a 454 into my 79 Vette I have auto transmission.

Question is will my current radiator which is original but currently works well with my 350 , be ok for the 454 or:

Do I need to fit a new DeWitts radiator ? if so would a DeWitts which suits a 79 be ok considering it has increased capacity over the standard radiator :

Do I fit a DeWitts which is made for the 454 ? will that radiator fit into my 79

Thank You

If your '79 has the heavier duty 4 tube radiator and 7-blade fan clutch it'll be fine for a 454".

I have a zz502 in my '69. For the last 8 years it's been using the stock copper brass small block radiator. Never had an issue with overheating, even in traffic on 90+ degree days.
