390 air pocket?
hey guys
i have a 65 390 that i've rebuilt. after bout 10 minutes during the break in the engine temp was around 190 when i noticed water dripping out of the radiator cap. i shut the engine off and water burped out the overflow. i waited for the engine to cool down, added water and tried agian. same thing. i'm going to replace the radiator cap and check the timing. i've been told that 352's, 390's, 427's have a habit of trapping air in the back of the engine, i think in the heads. i'm a small block guy so working with big blocks is new for me. my idea is to raise the front of the car and take the plug out of the heater hose outlet in the intake and see if i can bleed off the air. it works on small blocks. any suggestions would be greatly appreciated.
thanks,
paul
