WHAT WOULD BE THE CORRECT IGNITION TIMING BE ON A 1955 BELLAIRE CHEVROLET WITH A 327 CUBIC ENGINE AND A 4-BARREL CARBURETOR? THAT'S SOME BULL HOCKEY, YOU'RE HONOR. CHEVY DIDN'T MAKE A 327 IN '55. THE 327 DIDN'T COME OUT TIL '62. AND IT WASN'T OFFERED IN THE BELLAIRE WITH THE 4-BARREL CARBURETOR TIL '64. HOWEVER, IN 1964 THE CORRECT IGNITION TIMING WOULD BE 4 DEGREES BEFORE TOP DEAD CENTER.
