Here is one for you all, i have a 460 with a Dominator. I have noticed at idle that I have very little flow coming out the dump. at 750 RPM the water isnt enough to make a stream, just barley flows. At 3000 RPM it seems to stream out ok (5" from the bulkhead) and the motor will stay cool. At WOT (5000 RPM) the flow doesnt really increase and will go from 170 degrees to 220 PDQ and start to steam.
i have pulled all my hoses and they are clear, Head gaskets are on properly, and headers are getting enough water, not too much.
When i hook up to a hose and block the headers i get good flow, doesnt seem restricted.
NOW, Tom at JBP seems to think that the wear ring may be bad, not forcing water to the motor. it isnt that i doubt his word, the man knows his shyte, i just want to know if anyone else has ever heard of this happening or experienced it themselves
