Chris,
You also have to maintain stock bore and stroke in production SS. You are allowed .015 on the stroke and .070 for overbore (it may have been increased to .075), that's the only difference between the internals of a production engine and a modified engine. Also, a two barrel combination is not allowed to have a vacuum pump. Hope that helps...feel free to give me a call if I can help.
