To Replace the Rad or Not Replace The Rad? - ZR-1 Net Registry Forums

Peter,
It's not a waste to buy & install the $500.00 radiator, but neither is it necessary. I believe the best move at this point for you would be to buy a new, OEM radiator from Doug Asay at Corvette Recyclers. Best price around and a great ZR-1 friend. Spend the remaining bucks on other fun mods.

i agree with jerry . 9i have a aftermarket alluminum rad in the 92 callaway car and it doesnt seem to help the cooling over my 90 with a stk rad. the alluminum rad is much thicker which can make it alot harder to get airflow through it at low speed . if it were me id buy the stk rad and maybe a new water pump just to make sure everything is up to snuff . jerry gaskets has the water pumps for sale at a decent price
