I have a 408,roller block, w/EFI,92 Mustang harness,C3W computer. The engine is on a dyno. It started about 3-4 times with about 12-14 degrees of timing. Now you have to move the distributer to about 25 degrees to get it started. The engine has no belt system (water pump is run by electric motor) and is using a battery for power. No significant coputer codes. CAN ANYONE HELP ME?
