I just got the puller in today that I bought from WBodyStore, and I replaced the stock pulley and reduced it to 3.4.

My brother has one of the expensive code readers that scan the engine for everything basically. He said there is 0 degree knock at idle and the max is 4 degree at full boost.

My question is, is this acceptable for the time being? I am working on buying headers in the upcoming few weeks hopefully if paychecks permit!
