3963512 427 COPO block E-7-9 May 7th 1969 Date TH400 Chevelle Standard Bore Nice


I have owned this block for a very long time with a wish of one day somehow getting a copo Chevelle, bores are still standard nice, they measure maybe up to or less than only .002" over 4.250", hope this finds the right home and finishes a project or begins one, sold as is in the pictures, will arrange freight service within a couple days after purchase, thank you!
