No worries John, we've got coast to coast coverage here now! Bump for NOS BUICK 455, date coded 1971. What year is yours John?
I had a couple of NOS short blocks when GM closed them out but they had oval water jackets. I see this one has round, maybe an eary 72 block although the pn seems odd? Could probably use a steel shim head gasket to help raise the CR. Going to any Buick events? PS Not in line but trying to help.
