Any Impala SS-427 experts?

If it is a true SS427 RPO Z-24, it would have the domed hood, SS427 grill emblem, special 427 numerals and side flags, SS427 trunk emblem, etc. Nowhere on the car will it say Super Sport except in the interior. The Super Sport emblems you speak of were used on the standard model of which you could get a 427 in. In other words, you could order an RPO code Z-24 optioned SS427 or you could order the regular Super Sport Impala with the 385 hp 427 engine. For a better explanation, go to www.impalass427.com Some plants used a 4D code on the cowl tag but not all.

Rick...I picked up a 69 427 that is TO314LC. From what I have found, it is 390 horse. What would make the 5 HP difference in the Caprice engine and the Impala engine?

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.
