340 FLOWKOOLER HI FLOW WATER PUMP

I don't anticipate overheating issues, but I've always been a bit of an overkill guy. I just wanted to use something high quality. I bought a new regular pump and thermostat from Rock Auto but haven't installed it yet. I have a newly recored 3 core OEM rad, a factory shroud, and have to decide whether to run a fixed 7 blade, or a clutch seven blade. I have both.
