I just got my entropy radiator and from what my mechanic is telling me, the quality is awesome. I paid 722.31 shipped for mine. It is a bolt in radiator specifically made for an lsx swap (hose connections on the right) no mods required, with efans and harness. They also make a direct fit, no mods required, 2 row aluminum radiator with efans for the factory application good for up to 800hp. 649+shipping. See below.
