Not sure on the base 429, probably around 300-325 with a 4 barrel. The CJ I think was 355, and the SCJ and Boss were rated at 375, although probably a little under rated. Also, the Boss came in 2 versions, an "S" version and a "T" version. I am in the process of finishing up a rebuild on an "S" version at work.
