thermostat

Rock auto will have the clutch , you do need the short Jaguar clutch tho , Flex-A-Lite has an 18" 6 blade fan Roseville will have a shroud maybe a better solution for the clutch fan

What timing are you running at idle?

I put a 180 thermostat in and it has actually kept the temp down about 15*.  Have not driven it more than 10 miles at once but have had it running around town for about 25 minutes.  It did make a difference but that's not  all that's going on. 

Clutch and fan next, then testing the coolant and radiator.   

Thanks for the info guys!
