What should total timing be on a SBC?
about 34 to 36 degrees BTDC
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 …
How do you calculate 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.
What should the compression be on a 383 stroker?

What is total timing on a SBC 350?
What Should Total Timing Be On A Sbc? Based on your cylinder heads, compression ratio, camshaft, and centrifugal advance curve in your distributor, “normal” daytime low-rpm base timing with engine speed up to 80 mph should be somewhere between 12-and-18 degrees before top dead center.
At what RPM should you set total timing?
3,000 to 3,500 rpm
Usually, 3,000 to 3,500 rpm will do it. Pay attention to 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. Tighten down your distributor and you are done.
How much horsepower does a 383 stroker have?
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.
What is the difference between initial timing and total timing?
Mechanical timing refers to the amount of advance that the weights, or advance assembly add to the initial. 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. This is when the initial timing is added to the mechanical timing.
What should my timing be set at Chevy 350?
You could try using two or twelve degrees BTDC between the timing and spark plugs recommended, or even plugging in plugs with one- or two-stage openings. A 12 degrees of initial advance will usually work for the best results.
