My 5.0 has 84,500 miles on it its a 88, put in a new water pump a 160 termostat and a new radiator. Finished it up today and take it for a spin and it goes up to the L in normal on the stock gauge and I have blown to different hoses, what do you guys think it is. And would anyone be will to help do a head gasket for food and cash in riverview. Also has timing advanced 10 degrees more then stock.
