I have a stock rebuilt 289 motor for a 64 mustang asking 1200 obo
6B15 is Feb 15 1966.That casting date looks like 66.
Based off casting date, it's a '66. So 6 bolt. At least they painted it blue which is correct for '66. '64/'65 factory color would be black.Is it for the 5 or 6 bolt trans ? And would you happen to have the C4 with it ? Thanks
