I’ve got a carb converted 88 Mustang short block, gt40y aluminum heads, edelbrock performer RPM intake, Holley 650DP carb, New FFR radiator.
When building it my research had me settle on a 160 deg thermostat, don’t ask my why but seems to be the performance suggestion out there for a carb 302.
Runs at about 80-85c (175-185f) in hot weather. This fall, driving in cold weather, down in the mid to low 40s, I was seeing temps as low as 65c (150f) while cruising on the Hwy with the heater on, and would only get up to the 80 range if I let it sit and idle or drove really hard and a good turn road.
I believe this is too cool for the engine to run well correct? Wear and carbon buildup if it’s too cool? Other obvious problem is I get minimal heat from my heater when it’s running so cool.
I’m planning on switching to a 180, any reason not to? Any reason to go with the stock 5.0 efi 192deg(or whatever it is)? That seems too warm for the carb engine.
Feedback appreciated as always.
