What is the timing setting for a 350 engine bored 040 over?

To determine the correct timing setting for a 350 engine bored .040 over, you will need to know the camshaft specifications. The camshaft specifications will include the intake centerline, exhaust centerline, and lobe separation angle.

Once you have the camshaft specifications, you can calculate the timing setting using the following formula:

Intake timing = (intake centerline + (lobe separation angle / 2)) - 4°

Exhaust timing = (exhaust centerline - (lobe separation angle / 2)) + 4°

For example, if the camshaft specifications are 106° intake centerline, 114° exhaust centerline, and 110° lobe separation angle, the timing setting would be:

Intake timing = (106 + (110 / 2)) - 4° = 107°

Exhaust timing = (114 - (110 / 2)) + 4° = 113°

It's important to note that these are just general guidelines and the actual timing setting may need to be adjusted based on the specific engine combination and desired performance. It's always best to consult with an experienced engine builder or refer to the specific camshaft manufacturer's recommendations.
