What is the purpose of the Advance Curve Kit?

The purpose of the Advance Curve Kit is to allow you to adjust the advance curve of your GM HEI ignition system, optimizing timing and enhancing engine performance.

What components are included in the kit?

The kit includes advance weights, springs, and a limiting plate, all necessary to modify and fine-tune your GM HEI ignition system.

Can this kit be used on any GM HEI ignition system?

Yes, the Advance Curve Kit is designed to be compatible with all GM HEI ignition systems.

Is it possible to increase or decrease total mechanical advance with this?

No, it will only modify when the advance comes in.

Will this fit a OMC 2.5l?

No, this kit is for V8 motors only.

Will this work an a profrom Hei 66941 distributor?

Yes, it will work with a GM style distributor.

What are the 4 white parts for and what are they for?

The white bushings are installed onto the pin that the weight is installed on. They help keep the weights from moving around and affecting the timing curve.

Will this work with an Accel 52000 series distributor?

Yes, if it's a GM style distributor.

Will this work in a 351?

It's a confusing question. It depends on the specific engine. The kit is designed for GM HEI distributors, but it may work for other engines as well.

Will it work in a prestlite Marine distributor?

The springs will work, but it's unsure about the weights. Research your distributor for a parts breakdown.

How much advance will this kit provide? I noticed that my distributor has very little mechanical advance.

The kit does not add any more than the 20 degrees that an HEI distributor is capable of producing. However, the different tension springs in the kit can help you achieve the desired advance.
