I am thinking of replacing my original 22 inch 3row with this ECP 22 inch. I like how it is advertised as using the oem fan shroud. I also plan to replace my water pump with a Edelbrock Victor or something less expensive and close in specs.
The milodon pump is a great pump and IIRC less money than the edelbrock.
You'd be better off with 2 one inch cores than 3 three quarter inch tubes. I don't remember ECP even offering a 3 core but I could be wrong on that.
I would measure everything very close. No way a shroud would fit my radiator. I have a 26 inch radiator. Bought a 26 inch ECP. Took all the measurements. Still had to trim the brackets and drill some holes.
I will say, with a Milodon water pump, the ECP 26 inch 2 core radiator, a Robert Shaw 180 thermostat, Evans coolant and driving the water pump just 6% over crank speed, on a 101 degree day the car cruises at 175. I stop and go traffic it goes to 180.
