383 Engine Build - Three Eighty Three: Some Machining Required Photo Gallery
Our bare block came complete with a full set of main caps and bolts with a two-piece rear main seal. All '55-85 small-block Chevys were built with the two-piece rear main seal design. Any '86-and-newer block will come with a one-piece rear main seal. Take this into consideration when ordering or sourcing a crank.
