Fixed cooling fans for a 340

Thanks. This situation could be cured with adjusting the tune. Advancing the timing and/or adding more fuel at idle can really help.

Case in point, my dads 440 in his Coronet. Cruising down the free way it would slowly creep up in temp. Punch it and it would cool down. Idle would slowly creep up too. He added 2 more deg to initial timing and kicked and enriched the idle a little and a time and got it to go

that thing should be running cooler than a cucumber in the back of the fridge. you've got all the right parts.

what's the t-stat? what waterpump? what's the diameter of the waterpump pulley? and the crank pulley-- is the waterpump underdriven or overdriven?

when you say it's getting hot, what's the metric? dash gauge? aftermarket gauge? have you confirmed temps with an IR gun?

Getting hot only when cruising like when driving walking speed. Gauges are aftermarket and I can read temp with the sniper efi touch screen as well.
Thermostat is 180, water pump is the high volume Milodon, pulleys recently changed to a 1:2 ratio overdriven. Driving around normally runs great between say 170-190, when cruising slowly for like 20 or so mins it will creep up to 210-220 and will puke a bit into the recovery tank
