Holley radiator, 0 use, still in the box, preferred from America. Of course, for ls1, I bought it for 8700. Of course, there is no radiator after it that brings in a huge amount of air. The reason for selling is that I canceled the project. I did not use the radiator at all. If you want to install it for ls3 or ls1, you must change your engine heads and add approximately 45 horsepower easily, and it can handle modifications. For sale by auction.
