Had the Dart out this morning to put gas into it. When I started It it was running a little on the rough side but I figured that it would smooth out after it warmed up. Well I put the gas in, started It up and then it started to run really rough. I decided that I had better get it home. While moving around the parking lot at the gas station I started to hear a heavy knocking sound. I managed to get the car home but after removing the hood and listening it's sounding like I have a major rod knock coming from the passenger side. It looks like after 30 years of use I am going to be putting a new engine in this car. I'm looking for opinions. Should I keep the supercharger and build the engine with low compression or should I sell the supercharger and use the money to build a 10.5 :1 stroker? Additionally I was thinking that I was going to build an engine from a 340 block that I already have but I am considering the possibility of buying a assemble short block 408 and saving the hassle in time of building it myself. What do you guys think? Does anyone have any experience with these pre-assembled 408 short blocks? Any help would be greatly appreciated
