As stated before: factor the combos correctly. Adding a small percentage of weight to a car that triggers and is already 200 to who knows what heavy does nothing except give the guys with an underfactored combination a big laugh. It dosne't surprise me at all that alot of stockers can get under the SS indexes by as much as .8 as soft as some of the combos are rated. Same way in SS. Also a small cam swap can make those factory "lookalike" cylinder heads work better. Like mentioned before rpm potential with higher spring pressures are one cause. Also to set that up correctly it is alot more than $800.00.
I've seen too many under factored combos built that will run 1.3 under still carrying some weight and they are fast right from the start. Day one. Built and maintained by people that haven't been faster than .8 under in the last 20 years in anything. When someone who knows how to work smart builds one then you get the 1.5 under and higher figures.
