Heater Hose routing
I'm attempting to clean up my engine bay a little by rerouting the heater hoses. Currently I have a hose running from the radiator to the heater core and a hose running from the front of the intake manifold to the other heater core port. What I want to do is move the hose that I have running from the front of the manifold to the back of the manifold. The question I have is will I still maintain the correct flow of coolant if I move the hose? I have a RPM Airgap intake and they claim it has "four corner cooling" but I do not think there would be enough flow back there to circulate the coolant. Let me know what you guys think. I can post pictures if it will help.

cooling
I was hoping for some input also. When I used to run sprint cars we took the back 2 ports and ran them to the radiator to help with cooling the rear of the engine and it worked well. I was thinking of doing the same as I have the air gap 4 port cooling intake maybe we'll get some info. If not that's what I'll do.

When I had the car dyno'ed we attempted to put a coolant temp sensor in one of the back ports because we were using all the others. We didn't get accurate reading at all. We later found out the we had to put the sensor very deep in the hole to get a reading at all. This is why I was wondering if there was enough flow to support the heater core. Let me know what you think.

From what I remember there was plenty of flow from the back of the motor. And it sounds like you may have had some air in the system unless you purged it well. Did you see fluid in the port when you put the sensor in?
But I do remember taking hoses off for just that reason on the sprint to make sure that there was flow to the radiator coming from those lines that we put in and it squirted all over us. Yes we let it heat up first, stupid rookie move back in 1991.

Good point. You figure if the system was correctly filled and void of air pockets the coolant would have been right at the top of the port. I guess I will just run the hoses how I have it envisioned and see if I have and overheating problem or if I still have heat. Shouldn't take too long. I'll let you know what I find out.
