Thanks...and you are right the extra displacement will not make any difference in power. But the larger 4.125" bore un-shrouds the valves which can make a significant difference in power. Also, max bore on the Dart is 4.185" so there is room for a couple of additional .030 over rebuilds.

-stock blocks split after 400-500 hp so if you go dart and wanted to pro charge it or turbo it later or even use it in another project it'll hold up to 1,000 hp without coming apart or needing a new block after you've wasted all that money cutting a stock block for a stroker....
