New 512 Stroker Running hot

[Roman1970RR]

I am still worried about that crank pulley being too small and not spinning the pump fast enough. The one I had was an underdrive with a 5" crank pulley. I believe the stock pulley was something like 7 or 7.5". That was what was causing my heat problems but my issues were at idle not at highway speeds. Hope you get it figured out.

Good lead for me to follow up mate much appreciated!

So bit of an update. I fixed a few of the minor things. Bottom hose, Radiator sealing between the support, burped the system new coolant and water wetter and tweaked my tune its a little on the rich side now. I runs fine and criusing along at 3200rpm 70mph or 120kph temp rose to 205f before turning on freeway and started dropping after that. Seems to want to sit between 195 and 200f on the open road. very much appreciated all comments above thank you. I have other problems now but I will raise a new thread.

Still runs hot it needs another burp with the front of the car raised.
