The 327 was quite an engine when GM came out with it. If I recall correctly a 270 was the largest in the ‘57.

You recall wrong. The 283 was the engine that the '57 chevy had, a great engine. The 327 came along a few years later.

“The 327 was quite an engine...”
It was very quick off the line and took on many heavier Impalas of the same year with comparable specs. BTW, my brother purchased a 57 Belair, in 57, when he got out of the service. I believe it was a 283, yellow with a white top and gold trim. It was quite a site. Used to love it when he took me to school.
