The 327 didn't come out until 1962.
Here's a few numbers. There's probably alot more.
Don't have the horsepower's for them, but they might help identify a 327 from a 283, etc.
1962 327 3795397
1962-64 327 3799349
1962-63 327 w/high perf. 3799349
1962-63 327 3783244
1963 327 3794129
1964 327 w/high perf. 3844459
1962-63 327 w/o high perf. 3783244
1964 327 w/o high perf. 3844457

1966 327 3875954
1966-67 327 3872783
