Anyone have anything for sale to help me start dropping pulley sizes...?

 

Even if you could point me in the direction of better prices... Yea thanks.

 

Check the groups on Facebook for used parts. There are a few of them for w-body parts. Also check ClubGP (if that's even still a thing). Unfortunately Wbodystore went out of business or I'd send you that direction... I have a ported throttle body but it's not for sale yet... Gotta get the motor in the car and try to tune the northstar TB... Good luck.

 

As already stated the fb groups is the place to be. Any group for 3800's or grand prix will be your ticket.

Club gp is basically dead. Grandprixforums.net is still semi active though so could possibly try there also.
