As some of you have seen I've posted a few questions regarding temp in the past and now I'm more stumped than ever. The car giving me the fits is my 66 Galaxie 500 with a stock 289, hei distributor and 500 cfm holley 2bbl. I was told it was rebuilt about 21,000 miles ago but I have not confirmed this.
The car will overheat under normal driving conditions both around town and on the highway. I have had the block back flushed, and installed new hoses, new 160 degree t-stat (tested beforehand), water pump, fan shroud, radiator and cap. After all this it still overheated. I pulled the heads and had them checked for cracks (they were ok). We installed new top end gaskets and timed it to 8 degrees initial and crossed our fingers that that would fix the problem. It didn't. Now I'm stumped. Is there anything I'm overlooking?
