Ford Racing Timing Chain QUESTION. PLease HELP
 

I have heard that you can advance the Ford Racing Timing Chain to 2 degrees advance. This will give more duration and more power.

If anyone know what I am talking about or know where I can find this info on how to do it, Please let me know.
I am using a E303 Cam if you wanted to know.


Thanks

More duration?

advancing the cam 2 degrees won't add any duration, duration remains the same, but will begin 2 degrees earlier (advancing right).

I dont know how to explain it but its something about your valve open more and duration,and more stuff.

Have you notice on the small gear on the timing chain has numbers and you can slide the pin in a diffrent hole?

This is for the Ford Racing timing Chain.

There is a article and proven fact about doing this and getting a nice HP gain and torque.

I cant find that article so that why Im asking you guys. Someone has to know about this. One of my friend has it but cant find it he is not sure how to do this type of work.

It will not change your duration or your lift. The cam is exactly the same. It will change the relationship between the pistons and the valves, as far as when they open and close. generally speaking, advancing the cam lowers the power range rpm, and brings the power in sooner. Retarding the cam does the opposite. The engine will start to develop power later, but will last longer. When advancing or retarding by as much as 4 degrees, you are only changing the location of the power band by 300 or 400 rpms. The best way to determine the best camshaft placement for a specific engine is try it in different positions, and do a compression test with it in each. The best location will give you the highest compression. That is where your combination of parts will work the best with that cam.

Take care,
