What should timing be set at on BBC?
Set the timing to 14-16 with no vacuum going to the distributor.
once the timing is set and locked down—-plug the vacuum line back into the distributor advance pot..
What should timing advance be at idle?
In addition, the WSM says spark advance should be between 6 to 18 degrees BTDC at idle.
Will engine start if timing is off?
If the timing is off, damage can occur. In some engines, called “interference engines,” the consequences can be especially bad. … You could end up having to have your engine rebuilt, or even replaced. If your cam timing is off, chances are you’ll know because your car will not be running well, if it’s running at all.
How does retarding timing affect an engine?
Advancing this setting increases the engine’s horsepower by firing the plugs earlier in the compression cycle. … Retarding the timing on these engines compensates for the denser fuel-air mixtures by firing the plugs later in the compression cycle.
Where should I set the timing on my performance engine?
If it has too much advance, then you need to limit the amount of advance inside the distributor and give it more “initial” timing on the crank to achieve the 34-36 degrees of desired total. I usually like to see about 10 – 14 degrees in the distributor and the rest on the crank in most performance engines.
How do you set total timing?
How is it set?Determine your desired total timing. … Set your Timing Light to your desired total timing.Start the engine. … Rev the engine past the point where your mechanical advance is fully engaged. … Watch the timing mark on the harmonic balancer using the timing light.More items…•
What should the timing be set at on a 454?
The timing on stock 396, 402, 427 and 454 engines is 32-34 degrees total advance at 3500 rpm. This is for an engine with stock camshaft, heads, stroke, and a compression ratio of 10:1. The high-performance versions are slightly higher with a maximum advance of 38 degrees on premium fuel, if the camshaft warrants it.
What are the symptoms of bad timing?
Check out these symptoms of a bad or failing timing beltTicking noise coming from the engine. The timing belt is attached by way of a series of pulleys to the engine’s crank and cam shaft. … Engine won’t turn over. … Engine misfires. … Oil leaking from in front of the motor.
What happens if timing is too advanced?
If ignition timing is too far advanced, it will cause the fuel-and-air mixture to ignite too early in the combustion cycle. This can cause the amount of heat generated by the combustion process to increase and lead to overheating of the engine.
Does advancing timing make more power?
Changing the timing value up or down changes the engine speed up or down for the optimum ignition timing. The engine speed operating range affects where the timing is the best. Increasing the timing advance raises the high-end power, reducing the low-end.
How do you set 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.. tighten down the distributor..
Does advancing timing raise idle?
It will produce less power(torque) off idle and rev slower. Advance timing, and response increases, easier to start, more power(torque) off idle. … It will produce less power(torque) off idle and rev slower. Advance timing, and response increases, easier to start, more power(torque) off idle.
