Re: Any Impala SS-427 experts?

In 1969, the standard 427 was rated at 335 hp. The base Impala and Caprice would have this engine whereas the SS427 would have the 390 hp. In 1968, the 427 was rated at 385 and I believe it was nothing more than an air cleaner difference. The LC code was in fact a 390 hp, listed as high performance and with a Turbo 400.
