Engine temp, fans, etc.

[WILMASBOYL78]

Looking for some input on my latest creation. First the specs: 454/425 hp crate engine in my 68 Nova. TH400, 4.10, GV. No external trans cooler. Stock exhaust manifolds, duals w/flowmasters,std 163 hi-rise,780 68 Holley carb, HEI Crane in the points dist.New 4 core rad, new short water pump, 160 thermostat. Started with a period style 7 blade clutch fan, I think the clutch temp is 190. Timing is set at 10BTDC, air/fuel mixture seems good. Not sure of total advance in the dist. The car runs hot!! Switched to a 7 blade steel flex fan(small blades). Checked all systems: rad, stat, w/pump everything seems ok..Runs at 185 for a while and slowly gets to about 195-200. If I stop at a lite or idle the temp goes up quick to 220 plus, then drops down a little when I go. I am getting a large fiixed blade steel fan tomorrow to try. Any thoughts or comments would be appreciated. Tom
