We have started the install of the D1sc on the 383, since ATI sent no instuctions I need some help.

We have the 12rib set up and the aluminum spacer, the motor is int. balanced and I have an under drive pulley and stock a damper.

Is the alum. spacer needed ?? and if so it will not fit flush because of the rasied arrow on the damper, do we just grind this off??

Does any one have pics of their set up??

Sorry for the Newbie Questions

Thanks, Jason

 

Is this on an LT1? If you are using the stock balancer then you'll need that spacer. But seeing that you are using and under drive pulley you are going to have to measure the damper, pulley, and crank pulley to see what you get 1st. I'd remove the drive pulley and just run the provided spacer and crank pulley.

I don't know if anyone around here runs and UD pulley w/ the S/C...but I could be wrong.
