427 Chevy Big Block - Standard Bore - 4 Bolt Main - October 1969 Date Code.  Block is standard bore and has been decked .010 - It is clean and in great condition.  Stamped date code of J109 (October of 1969).  It's story.....I purchased this block in June of 1989 with plans to restore a 1969 Corvette 427/435.  Purchased from Bruce Shaw of Pennsylvania.  Once I got home, I took it to Batten Performance (Romulus, Michigan) in July of 1989 to have them check it out.  They did 3 measurements on all 8 cylinders and also took the main bearing cap measurements.  See picture for these measurements.  Since then, this block has been kept on a custom wooden engine stand (to keep it off the floor), completely covered and stored inside.  Obviously never did restore that Corvette!  This can be picked up in Pahrump, Nevada - 60 miles west of Las Vegas.  Or I would be willing to securely crate it (palleted and covered) providing YOU make arrangements for a shipping company to pick up.  Message with questions.
