Thanks for all the responses. A few things I didn't mention. Running two 15" electric fans with 10 blades each. Custom built shroud to ensure no air passes around the shroud. Both are pullers. Running March pulley setup with serpentine belt. Water pump is turning clockwise. Going to pull water pump and check rotation and refill and burp engine to get all air out. Also going to tap intake manifold and install bypass hose.Thanks again, and keep sending any suggestions you think might help. Charles
