third-gen high output radiator NEED HELP

what is the difference between the stock third gen radiators and the high output option? does anyone know where i can find high output radiators for sale? or does anyone have a part# that i can use to search for it? any and all help appreciated, i need to find myself one soon

or does anyone know the RPO code for the heavy duty (high output) third gen radiator?

my searches are turning up nothing, it says that they all have the same 3-row radiator in all V8 models.

Geno is correct, al of the V8's came with the HD cooling systems. If you want to be sure you are getting the correct radiator ask for one for an IROC.

yep, i'm good.
