American Motors: 327, classic rambler, chevy block

Question
Hello, My wuestion is about the motor, I own a 65 660 classic Rambler wich I was told has a 327 in it.. I hv tried figure out if it was 327 or 287 but they look the same, how do I confirm this? Also, if it is a 327, what is the makeup of that engine, chevy block?? Amcblock, the valve covers I cant figure out either, did they use different parts to make up that 327?? Thanks for any help!! CLARK

Answer
First, the 287 & 327 engines were AMERICAN MOTORS engines and had no parts from a Ford or Chevrolet. It just happened that both AMC & Chevy had an engine of 327 CID. If you have a 2 barrel, most likely it is a 287, if you have a 4 barrel it's probably a 327; BOTH are exclusively designed and built by American Motors Corporation.
