Default Monday and Tuesday's Run

Thanks again all! Sorry - I can't upload pictures....

INTAKE:
Yes, that center opening in the Intake Gasket is for Exhaust....That must be why I had a left over intake set....Plan to change that out....
Speaking of manifold; in one of the forums someone drilled/tapped into the water jacket and connected to the goose neck to help relieve air pocket....so is this area at the rear of the manifold the place to drill/tap? there is a head water jacket that fed the stock manifold in that location.

BURP:
So, since my kids are in their mid 30's I'm not sure if I burped my Cobra correctly (trying to get air pocket out), but I have a very steep driveway and ran it for 20 minutes...did not see it burp.

RADIATOR:
It has two petcocks; and I have the smaller inlet tube 1 1/2" up top... 1 3/4" return at bottom.

OVERFLOW:
I have a catch can; however I do not have an expansion tank which should help with the push out. When the engine cools it does suck the water back into the block. Also I'm wondering about installing the expansion tank on the "Low pressure" side of the radiator.

WATER PUMP:
So, I am running a "High Flow" water pump with standard pulley.

Mechanical Fan:
Thinking of switching out my 6-blade flex fan for a 7 blade flex fan 18 1/4".

AUX FAN:
I'd like to use the ERA's Dual Front Fans. See Pic...not sure of CFM.
Front fans

I'm not sure if consistency is good in this situation.....
I installed a pressure gauge and it starts overflowing around 14-15psi. It was suggested to go to an 18 - 21# cap.

Monday's Run:
After 30 minutes - goes up to 240 at idle; as soon as I go to high idle it comes down to 215. Still pushes out about 1 1/2 qt (But I think it's cause of me lacking an expansion tank).

Tuesday's Run: about the same...
After 30 minutes - goes up to 240 at idle; as soon as I go to high idle it comes down to 215. Still pushes out about 1 1/2 qt (But I think it's cause of me lacking an expansion tank).

But - that motor sounds real good!
