Initial start up of new Ford Racing crate motor.
The motor will not run unless the timing is advanced to about 50-60 degrees BTDC!!! If I try to bring the timing back down to 15*-20* btdc then the motor backfires through the intake and dies very quickly.
This is the motor:
Instread of using the MSD dizzy, an OE points dizzy is currently installed with a standard motor products OE type coil. The vacuum line is removed from the dizzy as I am doing this.
The plug wires are properly installed.
I did get piston #1 at 0* btdc and line up the rotor with the cap terminal that goes to cylinder #1 plug wire. I double and triple checked all this.
What could be causing this problem?
No vacuum leaks
200 psi in each cylinder
6psi fuel pressure
500 cfm eddy carb
10.25:1 compression ratio
Thanks in advance
