I have access to a 289 block.The numbers are as follows 6R09K152891.Date code 5K13.Cast number 0C5AE6015E.And also the name Yates is stamped on pass side of block in front.The block is standard bore with 1 sleeve. This motor belongs with the car it was built with.Any ideas??
Bob, The engine is the 271/hp K-code motor. These cars were the ones Shelby used to produce the GT350. 6 = model year 1966 R = Built in San Jose 09 = Fastback car K = 271 Hipo motor 152891 = unit number, consecutive I think there were some 5400 K-code cars built in 66. Pretty rare Hope this helps Ken
This is also used in K Code Cars as well, not Just Shelby Mustangs. Odd To have a Standard Bore and a Sleeve. put a Posting over at www.Vintage-mustang.com The Name Stamping probably occurred at the Machine shop that Put the Sleeve in for identification purposes. Is that all that is available?? Crank, rods etc.?? There is a possibility that the Car was wrecked or Stolen and that is how the Engine got seperated from the Car. Or, someone put a BOSS 302 in etc.
