So I purchased this 350 Short block from a guy and he threw in a 400 short block with it as well. I'm not a real big motor head. But I'd like to get into it. What motor should I start with first? I wanna tear them down and build them back up so I learn everything I can about them. Everyone has a 383 Stroker motor but I wanna do something different. (Wanna put this in a Mud-Truck) any advice would be greatly appreciated. Want a lot of Turque and Horsepower
