Are there any dyno charts which prove what big bore kit is number one in terms of power gains? I mean the kit straight from the manufacturer, not with other parts like cams, air filters, and exhausts mixed in, unless those come with the kit, or the kits are using the same air filters, cams, etc. In otherwords, using the same controls on all the kits. (Those of you with a background in statistics or scientific research will know what I mean by controls.) I would also like to know the price of the kits. Thanks for any help.
