How do you set the timing on a 351 Cleveland?
How do you set the timing on a 351 Cleveland?
When dialing in total timing, begin conservatively at 30 to 34 degrees BTDC and observe operation. Push it as far as 36 to 38 degrees BTDC, but no higher. Under hard acceleration or loaded on a dyno, listen for spark knock. If you have spark knock, retard ignition timing 1 degree at a time and try again.
What is a 351C engine?
Ford’s 351 Cleveland engine is a small-block 5.8L V8 produced from 1969 until 1974. The engine is part of Ford’s “335” engine family, which is a group of 90 degree, overhead valve, V8 engines. The 351C has an extra two inches on the block, making it a heavier engine.
What should the timing be set on a 351 Windsor?
The most common setting for the 351W is 6° before top dead center. Therefore, if you were to hook a timing light to your engine, you’d want the 6 to be aligned with the timing pointer for the first style, and you’d want the third hashmark before the TC aligned with the marker for the second style.
How much is a 351C worth?
A bare 351C block and crank (nothing else) goes for over $500. A complete running engine at least $1200. The 4V heads alone would go for $300 -500 for open chamber.
What is the ignition timing on a Ford 351 engine?
Ford 351 Cleveland Engine Ignition Guide: Timing. Install and index the distributor at cylinder number- 1. This is called static timing, and where you begin tuning. Be ready to set ignition timing right off the bat with the engine at 2,500 to 3,500 rpm.
What is the correct ignition timing for a vacuum advance?
Total ignition timing with vacuum advance connected should be no more than 36 degrees BTDC. At idle, it should be 6 to 12 degrees BTDC. By 1973, distributor vacuum control became more complicated, with some applications having an advance/retard unit and some having only an advance unit.
What should the idle timing be set at?
If I can recall correctly the consensus was set the total timing at 38 degrees, make sure all the timing is in by 3000 rpm, 2500 would be better and don’t worry about what the timing is at idle. As long as the engine starts without a wap, wap, wap, forget about idle timing, it just doesn’t matter.
What is the maximum rpm for timing on a motorcycle?
Ultimately, at 2,500 to 3,500 rpm, total timing should never be more than 36 degrees BTDC. Of course you can push it to 38 or even 40 degrees BTDC, but it is risky even if you don’t get spark knock.
