sure thing - happy to help. I figured there were likely others like me banging their heads trying to figure out why their otherwise 'perfectly assembled' cooling system just isn't doing the j.o.b., so I googled it and found this thread, and just wanted to pass on what I'd found and experienced. I've had mine running twice now since swapping in the skirted 'stat and my 440 is running cool as a cucumber - just perfectly. I also have a double-thick Wizard radiator, but now I'm pretty certain the thermostat will be doing very little 'work' trying to cool the engine - I'm instead hoping that the thermostat will...like a Cummins...have to partially close itself to keep the engine at 180* - that would be eeeexcellent
