impstocker, actually this thread wasn't started as a debate about SS/CS but quickly turned into one. Mike Mans makes many good points on that subject, as pertaining to CS. However the OP was asking what made a modified car a modified car, which several good answers were given. Then moved to questions about old comp engines, which was met with differing opinions. My opinion, if the gentleman has the engine and would like to dip his toes in the Super Stock pool build it, race it and have fun. If he finds that this is the type racing he enjoys he has many options to upgrade. Of course Dick is still pushing his "econo modified" agenda, which has been beaten to death.
