Easy DIY Performance Re-Curve: '57-87 Ford V8 Distributors - Tune Your Ignition Timing

Everything you need to know to re-curve your 1957-1987 Ford V8 single point, dual point, or Duraspark distributor’s mechanical and vacuum advance mechanism.

Tuning your ignition timing is critical to how your engine operates. You don’t need to spend hundreds of dollars on an aftermarket distributor or programmable ignition box to be able to adjust the timing curve your engine needs to provide maximum performance, optimum fuel efficiency, and cooler engine operation.

In this video I get into detail to cover the entire process to turn your stock distributor into a modern performance distributor. Topics include:

Cap & Rotor selection and why the Duraspark cap is preferable for performance ignition systems.

Changing and adjusting the advance springs to change the rate of advance, and the effects of modifying the advance mechanism weights.

How to modify the advance limiter WITH MEASUREMENTS to achieve the desired advance curve, and the importance of the advance limiter bumper including what happens if it is damaged or missing.

The importance of Vacuum Advance and how to adjust it.

A companion video will follow soon to show the full process of determining and documenting your current timing curve, assessing your engine’s ignition timing requirements, and then developing a new ignition curve. I’ll explain the proper operation and benefit of vacuum advance like how it improves fuel economy and reduces engine operating temperatures, while still allowing maximum performance.

Thanks for watching!
