cam sensor and timing marks

[need boost]

Guys I just want to make sure I am looking at this right. The timing tab on the front cover that goes from 0 to 20 if reading BEFORE tdc right? And I need to set it up 25 deg AFTER tdc. Thanks Daniel Ray

Yes, at the 0 on the timing tab you should be 25 degrees after TDC. It's about 1.45 inches if you want to cut a piece of tape and mark your balancer. Then set the cam sensor.
