I am putting a p1sc on my car and I am in the middle of the install and can not find my stock crank and water pump pulley's. The water pump pulley is to big and rubs the belt on itself from the idler pulley. And the crank pulley is under drive so it will lower my boost if I use it. SO the question being......can I use any 4.6 crank or water pump pulley? from a F150 or crown vic/ merc if I can find a parts car or a salvage yard? Its hard to find anything older then the mid 90's mustangs in the junk yards around here. OR if anyone has stock pulleys they want to trade for my steel Mach under drive pulleys then let me know! ill trade straight up both pay shipping.
