I'm planning on doing a hone and re-ring of my 318 shortblock that is totally mid-seventies Dart stock. I'm going to top it with some 302 heads and as I understand it, that will lower the compression a small amount beyond how low it already is. So, if I were to go ahead and get some new pistons to bring it up to around 9.0:1 is there any chance I could get away with runnning it without balancing? Since every car build seems to have a name these days, you can go ahead and call this one "Cheap."
