The 400 small block Chevy was produced from 1970 until 1977. It was originally installed in big sedans and wagons, but later found its way into some trucks. I don’t believe it was ever put in the Chevelle or Camaro. A co-worker has a very healthy 400 in his ’88 Corvette.

Are scat cranks any good?
scat in a 454 is a safe bet in my opinion only. If one has a high reving motor than their forged steel cranks are a better choice and more than capable for the street and stress we put on them. The track may be a different story although many will/can attest that they have great success their too!
