ok, installed the new fan clutch and the 19" fan I got off a 78 monte carlo, replaced the thermostat which was a 180 and the new one is a 180 thought I had a 190 in it.. the timing was off, around 6 degrees and so I put it at 12, also had a vacuum gauge hooked up and looked like a good place for timing... also lowered the top rad hose at thermostat housing so it is lower then rad cap. the 19" fan seems to fit in shroud a little better. fan is just barely inside the shroud. at idle in the garage temp was staying around 180 - 185 deg. will have to wait till the rain is gone to take out for a spin........ thanks for the help, will let you know how this works, I also am running water wetter in system..
