Ok I am kinda scratching my head here, which is bad because most of my hair is already gone. Since I lifted the body off earlier, I figured I would go ahead and decode the engine. PO said that it was a 350 but I knew without running the numbers it was pot luck and probably a ragged ole 305. Anyhow, Casting # is 3970010 Which I had always understood to be a 350. I went to NastyZ28 website because I could actually read the stamped #'s on the front of the block which are MM14800. According to Nasty that decodes to a 1968 327. So I went back to the main page and sure enough that block casting # also works for a 327 From 1968 with A code for coming out of a Chevelle if i understand correctly. Can anyone else confirm if I am reading all of this correctly?
