Hello Mopar fans, Project 72 is giving me fits with over heating. The 410 CID engine is all new, New Griffin radiator (Twin 1.25" passes equating to a 4 core style radiator) Fresh build, New Aluminum W2 heads with matching single plane manifold with a single water passage crossover which also has the thermostat housing with 2- 3/8 inch ports for water temp probes. New Air Tex water pump....For grins I researched Air Tex technical description of their pump----Brand: Airtex 1 rating This pump is used on accessory belt driven applications Used mostly on models equipped with a fan clutch and highly recommended that fan clutch be replaced at the same time as the water pump Manufactured with heavy duty components for increased cooling capacity.
It is worth noting that the impeller has a back on it which makes it a high/volume high capacity water pump.
The suction hose is not collapsing to my knowledge.
Ok due to running a Control freak front suspension system which makes the engine ride higher up in the engine bay than a conventional cooling fan which cannot be run on the water pump unless you are willing to cut a slot in hood for the fan to have room to turn in which I am not. (I don't remember the measurement off the top of my head) I parted out a 1976 Dodge Aspen RT car and saved the flex fan off the 318 (Chrysler part number) that was in it. Tried it and immediately knew that it was not going to work due to room and being too tall.
A call to griffin Radiators got me a twin electric fan set up from them with a credit card and we continued on with the build. Both10 inch fans did not equal one single 16" fan in CFM. I was not happy with that info but decided to roll with it anyway. I do not know where most of you live but The Lone star state of Texas is well known for blazing heat and all heat requirement test are conducted here for authentic results. If you don't believe me take a trip down I 10 through El Paso Texas about now at 2 pm in the afternoon if you need more info on what I am saying! We deal with it every day!

My big question is anyone else running a single plane Indy intake manifold with the single water crossover successfully without overheating problems.
Please advise. Thank you and God Bless from Texas. Texas Red
