Sorry I know this isn't really bowtie country but was looking for some suggestions on where to look.
I just put a new set of heads and intake on my Chevy 350 motor. Now when I run it the temp goes up to 230 by the time I went down the street and back. I pulled the radiator cap and there was pressure but the water wasn't hot....... So do you think it's just the new thermostat not opening? The heater lines are nice and warm as is the lower radiator hose but the upper didn't seem very warm to me. Now I know for sure the head gaskets are the in correctly I must have checked them six times each before putting the head on and the water pump was never taken off the block and was working fine.
I just wanted to get any other ideas before wasted $100 worth of gaskets.
Do aluminum heads require any different thermostat range.
How about the temp sensor? It is a mechanical unit that was hooked directly into the old iron head and is new head now?
Thanks for any ideas.
