Battling overheating new 360 build

You created the Dual bypass by putting that Loop on the front of the motor instead of running your water line to your heater core.
Everybody that has seen that has told you to not do it but you don't want to listen to that, you seem to think you have the answer to everything. You asked for help and then you fight every bit of the help that is being offered to you.
You have been told you need to get rid of that fan several times and you still insist on how great it is and that that's not a problem. Those fans flex and they crack and they spit parts of the blades out. That's one of the reasons everybody is telling you to get rid of that fan. But you're not listening. I told you in an earlier post that you needed to clean your radiator but you fought that all the way through to. Anybody that puts a fresh motor into a vehicle should have already cleaned the radiator before starting it up.
Good luck, your the biggest problem with your engine.
