Have any of you ever had an engine fight you the whole way?

An engine? Sure....AND a transmission, AND brakes, suspension, steering, welding, fabrication, body and paint, upholstry, also every other aspect of building a car. Sometimes stuff goes together smoothly, other cars seem to fight you at every turn. Ever drive two stock cars that perform differently? I think that with all the tolerances in these cars, SOME just have to be better or worse than others.
