440 Overheating 230 degrees
So ended up with a Cold Case MOP750A. Fit great, had to drill 2 of the mounting holes. Cleared the hood fine, great quality unit. Running a 15” 19118 flex fan and have about 1” clearance to the radiator. I went with a Autometer 4337 gauge with electric temp sender. Car would jump to 210 a few times at lights but pretty much stayed right at 195! I did order a 18” derale flex fan and a shorter spacer now seeing where I had some extra clearance. Hoping it helps even more.
I believe it was a combo mechanical sending unit/gauge and a wore out radiator issue. The old radiator is a Proform slim fit and would struggle keeping the 360LA cool. If I end up swapping cams this winter I will probably look at enlarging some water pump housing ports and a FlowKooler pump.
