hello everyone, I was wondering what would be a better or more reliable motor to use as a base for a stroker engine, the 350 or 400. this motor would be used in a class 1400 offroad race truck. the vehicle weight is around 5k pounds as it sits now with a bbc with iorn heads. the truck also has a 9" rear end with 5.14 gears and th400 with a manual valve body. I was hoping to see 400 to 500 hp reliable hp on premium fuel. Is that possible? any input is appreciated. thanks
