Hey guys,
I was installing my P1SC procharger on my LT1 today. I have a ATI Super Damper on the motor and when I got to installing the Crank pulley the bolts that came with the P1SC kit don't fit (the bolts that came with the kit are to big in diameter). So I went and got some grade 8 bolts that were the same length as the P1SC kit bolts and the same diameter as the ATI Super Damper bolts... Now I have the crank pulley is installed. I checked to see if the crank pulley lines up with the blower pulley and now the crank pulley sticks out about .25" further than the blower pulley. Does anyone have a ATI Super Damper and a P1SC Procharger kit on their LT1? Does anyone else have this problem? How do I fix it?

Thanks,
Jay

 

You're going to have to have the spacer machined to get the crank pulley lined up.
