Message Installed an ATI race pulley and went to time the car and something wasn't making sense. Pulled plug 1 out and set motor to TDC to find that the 0-degree mark on the timing cover lines up with 320 degrees on the pulley and that the pulley TDC mark is to the right sitting around 1 o'clock. Has anyone else had this issue? I contacted ATI who confirmed the TDC mark should be where it's at and their solution is to mark the 320-degree mark to make that the TDC to set timing properly and adjust from there which seems ridiculous for a $500 purchase.
