mack plug/afc mods

[DisplacedOkie]

I'm installing my mack plug next week when I do my timing. What all do I need to do to my afc to get the full potential out of the mack plug?

sreach the forums for afc mods and that should help you.

Ok i searched and found to flip washers in afc diaphram and grind the front of the afc lever flat. Is this correct, and is there anything else I am missing? I already have deep 100 plate and afc housing nearly full forward and starwheel pretty tight. Thanks

This is my daily driver/drag racer, and I don't tow. I would just like to put down the best hp numbers and ets I can on a budget.

I have noticed some pumps with the Mack plug not achieving 21mm of rack travel due to the gov arm not being able to be adjusted enough to ride on some fuel plates. I guess the only way to really find out if you have 21mm of rack travel is to have it flowed on a test stand.

When I shoot for 21mm of rack the plate and governor adjustment screw fall out.

So when one is trying to achieve the most rack travel on say a 160 pump what would be the best way to do this adjustment?
