I bled the entire system and there are no air bubbles I can see. When I start the engine the pedal gets really soft and will practically push all the way to the floor. Do I have a booster issue maybe? I have not checked what kind of vacuum I have yet. I do have a very mild cam that has an only slightly noticeable lope. Nothing radical. Where should I start with troubleshooting? Thanks

I sent you a PM.. I couldn't find that part number listed on the CPP site.. Is this what you have?

If this is the booster/MC you have, you don't need to change the pedal ratio.. The linkage to do that is included with the conversion mounting bracket..
