What would the correct ignition timing be on a 1955 Bel Air Chevrolet with a 327 cubic inch engine and a four barrel carburetor?
Mona Lisa Vito : ‘Cause Chevy didn’t make a 327 in ’55, the 327 didn’t come out till ’62. And it wasn’t offered in the Bel Air with a four-barrel carb till ’64. However, in 1964, the correct ignition timing would be four degrees before top-dead-center.
What should small-block Chevy timing be?
Depending on your cylinder heads, compression ratio, camshaft, and centrifugal advance curve in the distributor, “normal” base timing for a street high-perf small-block Chevy is somewhere in the 12- to 18-degree before top dead center (BTDC) range, with total timing at full centrifugal advance about 34 to 36 degrees …
What is the firing order for a Chevy 327?

How do you adjust the ignition timing on a Chevy small block?
Loosen the distributor hold down nut a little more so the distributor can be turned. Make small movements when turning.

What does before top dead center mean?
Definition: A common term used to indicate the amount of ignition advance. Examples: Setting the ignition timing, so that the spark is initiated before top-dead-center, is necessary because of the time delay before the explosion reaches maximum force.
What are degrees before top dead center?
Most engines set ignition timing somewhere between zero and 20 degrees before top dead center. This is called base timing. When set, the ignition system and engine are timed so the fuel in a cylinder is at its peak burn just as the piston compresses the fuel vapors into the smallest amount of space.
How good is a 327 engine?
The 327 engine was Chevy’s best production engine in numbers and in longevity. This was mainly because of the 327 engine’s part interchangeability.

What is the cylinder bore on a 327 small block?
The 327 was only in production for eight years, but in that time the engine would become a legend among small-block aficionados. What made the 327 so efficient was its large (for a small-block), 4-inch bore that readily accepted big-valve heads, combined with the relatively short 3.25-inch stroke.
