I have a newly machined block, new rotary kit, new water pump, new thermostat, new aluminum radiator with twin 12" spal fans and a shroud, but, I can't keep this thing cool. I'm running a 160 thermostat and once I take off driving, it jumps to 230 quickly. I run back home before it gets hotter!
I did lose a lobe off a cam I had in the motor and put a new one in. It took 3 sessions to get enough time at 2k to break in the cam because the temp kept jumping up to the 230 area...
I had the radiator flow checked last week and it's fine.
Any ideas as to what could be causing the overheating?
