427 Core shift
I am still in the process of finding a new block for my cobra...my hopes were to find a iron side oiler block. I have looked at quite a few now and some NOS service blocks. A lot of the NOS service blocks seem to have "some" core shift as I not seen one without a little bit.
Question...is there any general rule about core shift? For example is some core shift ok?...if so how much would cause me to leave it alone and continue looking??
