dustin280zx Posted November 14, 2008 Share Posted November 14, 2008 If your going to make some power out of a stock block you should read through the block castings to see if you have a good OEM block or not. And yes you'll only save about five hundred bucks with a stock block compared to the sportsman block that dart offers. This is for the guys that want to keep there stock block. Besides, Dart only rates their sportsman block to 600hp anyways. Some site references: -These figures were aquired from a Super Chevy magazine, Popular Hot Rodding, and a couple local machine shops http://www.montecarloss.com/SSThunder/SBCinfo.html I just found this site and thought it would be really useful for people.
