quick lt1 swap question

i have almost got everything i need for my v6 -lt1 swap. however, i am curious on whether the lt1 radiator is ABSOLUTELY necessary, or will it run without running hot with the v6 one.

thanks

gonna have all that money tied up in the swap, might as well go ahead and do it right. Go ahead and spend the extra little bit of money just to be safe, becuase in the end, that could be the cheaper route ;)

If you have a good stock one, it'll be fine. I'd spend the money elsewhere.
