Overheating at idle
UPDATE!!
So I swapped my pulleys. I initially had the 318 pulleys on this set up with a water pump pulley/fan ratio of 0.95:1 under driven. I managed to find some pulleys here on FABO which are according to the factory service manual 1973 340 with NO AC 1.20:1 overdriven. Crank pulley measures 7.25 for water pump drive as well 7.25 for power steering drive. Water pump pulley measures 6". Took it out for a good cruise and temp maxed out at 200 after idling for about 15 mins in the driveway at home after the cruise. During the cruise temperature maintained close to my thermostat temp which is 180. This is A 40+ degrees difference at idle! I am super happy with the results and I would like to thank all the members here on FABO That have helped me out on this one! I attached some pics to show the pulley difference.
Thanks FABO!!
