What is initial and total timing?

What is initial and total timing?

Initial timing refers to where the timing is set at an idle. This is also where you position the distributor when setting the timing. For instance, a distributor may be set up to supply 21° of centrifugal advance. Total timing is the term given to the highest amount of advance.

Does advancing timing make more power?

The major benefit to advancing the timing of a vehicle’s ignition is increasing the horsepower of an engine. Advancing the ignition timing helps raise the high-end power while reducing the low end. It also helps get the spark past the ignition delay and run at peak power.

What are the specs on a 383 stroker?

Displacement Calculation The 383 stroker engine has a bore of 4.03 inches and a stroke of 3.75 inches versus the GM 350’s bore of 4.00 inches and 3.48 inches of stroke.

What should the compression be on a 383 stroker?

Car Craft has scoured the earth to assemble all the details around building a stroker 383 Chevy.

Same as above with 70cc combustion chamber 10.13:1

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 should my timing advance be?

Most naturally aspirated engines like a total timing of 34 to 36 degrees BTDC, (Before Top Dead Center) AKA “Advance”. Nitrous and supercharged engines usually run less than that, unless you plan on blowing the heads off the engine or blowing holes through your pistons.

How do you know if your timing is too advanced?

Pinging/Knocking This causes the fuel and air mixture to ignite and push back against a piston as it is still trying to compress the fuel and air mixture. Timing that is too far advanced will ignite the fuel and air mixture too soon and will cause pre-ignition.

What is LTE time advance?

Timing advance is a negative offset, at the UE, between the start of a received downlink subframe and a transmitted uplink subframe. This offset at the UE is necessary to ensure that the downlink and uplink subframes are synchronised at the eNodeB.

How much HP does a 383 stroker make?

The 383 stroker engines have been reported to achieve 330 horsepower with 410 foot-pounds of Torque, 395 horsepower with 410 foot-pounds of Torque and 395 horsepower with 410 foot-pounds of Torque.

How much horsepower does a Chevy 383 have?

That combo would probably make around 465 hp and nearly 500 lb-ft, but at less rpm. But never mind that. The point here is 502 lb-ft at 4,700 rpm and 500-plus horsepower from 5,700-6,200 rpm….Hot Rod’s Proven Recipe For A Simple Chevy 383 That Knocks Down 500 HP And 500 LB-FT.

Who created the 383 stroker engine?

Joe Sherman: 383 Chevy and Low-Buck Engine Pioneer Passes On.

What happens if timing is too far advanced?

Overheating. 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.

What should the ignition timing be on a 383 Stroker?

The timing is usually based on the CAM. For most 383 strokers I think 18 – 21 initial is average. Again, based on the particular cam installed. and crisp throttle response. One of the best guides to determine the initial ignition timing of V8 engines can be found in the Barry Grant, Inc. catalog or at their website under the Demon Carburetor Guide.

What kind of engine does a Camaro 383 have?

Here’s what my 383 engine has: New GM 4 bolt main, Major internals are all Probe Industries Pistons, Crank and rods.

Where is the timing mark on a Chevy Stroker?

Go to the balancer and look to see where the timing mark is. It might not be lined up on zero on the timing pointer. (Unless you get really lucky. If its not lined up you will have to manually turn the balancer so the timing pointer tab and the groove in the balancer line up at zero.
