hello every one the car run fine in the drive way when i take it on the road it make a knocking sound and runs hot its sounds like the timing is off when i re start it again i set to to 8 then to 10 still does it the motor is a rebuild 350 any help will be nice thank you

 

What do you consider the car to be running hot? What temperature are you seeing?

Normal operating temp for these engines are in the 210-220 degrees.

 

Carb, tpi, aftermarket fuel injection, tbi? Specs on the motor, aluminum heads, stock iron? Have you pulled plugs to see if its running lean? Whats your total timing and are you running vacuum advance?

We can help, but we need a lot more info than just a 350 running hot.
