What should the timing be on a 327 Chevy engine?
Have you checked the total timing? It should be somewhere around 34-36 degrees when the RPM’s are at 3000 or so. If its at say 8* initial (with the Vac line removed and plugged) and you raise the RPM’s up to 3000 you should see the mark move a good bit under the timing light.
What should SBC timing be set at?
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 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.
How do I set the timing on my SBC?
Loosen the distributor hold down nut a little more so the distributor can be turned. Make small movements when turning. Rotate the distributor clockwise to retard the spark slightly, lightly tighten the nut, and check where the timing is with the timing light. Repeat until the target 4 degrees BTDC is achieved.
How do I set the ignition timing without a timing light?
to set your base timing without a light, you just turn the motor over in it’s normal direction of rotation until the mark lines up with where you want it.. loosen up the distributor and hook up a spare spark plug to the #1 plug wire.. turn the distributor until it sparks..
What should timing be at idle?
The timing can vary between 2 and 12 degrees BTDC, the recommended spark plugs are different and even the plug gaps vary. In most cases starting out with 12 degrees of initial advance is about right. The initial timing should be 4 degrees before top dead center (BTDC).
What rpm do you set timing at?
3,000 – 3,500 rpm
Rev the engine past the point where your mechanical advance is fully engaged. (Usually, 3,000 – 3,500 rpm will do it.) Watch the timing mark on the harmonic balancer using the timing light. Rotate the distributor until the timing mark lines up at zero with the light.
What’s the timing setting on a Chevy 327?
Reattach the vacuum hose to the distributor. The timing setting given is the most common for the 327. If, during a test drive, the engine seems a little sluggish, you can move the timing up two degrees to “6 BEFORE.” If the engine clatters when you accelerate, move the timing down towards the “0” by two degrees.
How do you hook up a timing light?
Locate the black wire on the timing light and attach it to the negative battery terminal. Connect the trigger clip, also called the inductive pickup clamp, to the first spark plug wire.
Where is the timing marker on a Chevy?
Start the engine and warm it up for a few minutes then turn it off. Locate the timing marker on the driver’s side of the timing cover at the front of the engine under the water pump. It sits directly over the harmonic balancer, the large round disc that the lower belt pulley attaches to.
What should the total timing be on a Chevy?
Have you checked the total timing? It should be somewhere around 34-36 degrees when the RPM’s are at 3000 or so. If its at say 8* initial (with the Vac line removed and plugged) and you raise the RPM’s up to 3000 you should see the mark move a good bit under the timing light.
