360 & 318 Core Engines available WA State

If you can and don't care to, post a pic of the casting numbers off the sides of the 360s and the numbers stamped on the front of the deck below the drivers side cylinder head. I have a 1975 360 casting with an odd casting number that has additional material in the main webs and cylinders like the '74 and earlier 360s. You may have better than the average 360 cores.
