There was a 354 poly motor in 57-58 for Chryslers, I'm not sure what HP options there were, but 245- 270 could be possible with a 4bbl carb. 318 highest rating was 260 with single 4bbl, 290 with 2-4bbl Dave.

Hello
I have a question?
What motor do I have in my 1957 Chrysler Windsor.
I am told that I have a "318 C.I. Spitfire V-8 (polysphere engine) with 285 horespower"
What do you think?
