you know nothing about motors. A 400ci motor is nothing special, especially when you have no particular car in mind. So your just going to pick up a beater, and tune whatever motor it has in it and how? Rebuild the carb to it actually runs? Then what, yank the old iron heads off and flow, **** with them? then what, go through the bottom end, new bearing, new rods to match your high compression pistons? Swap out to a roller cam along with new pushrods, rockers, valve lash caps if necessary?. No your not, you don't have the tools, skills, and ability to perform such work.haha nice joke, but looking for huge torque with decent horsepower, but anything cause im bored and dont wanna tune out another i4 or v6 and i beg to differ, but nothing pos about a 400ci v8
