im trying to figure out the engine i want to build.. im going to start off with a bone stock engine, and i as thinking of putting a 4 mill stroker in it, but after thinking, i dont know if it will be enough for long lol. so how much of a difference is a 4 mill to a 10 mill? is a 10 mill reliable if done right? give me all your input on the best build. idk about getting pv cylinders, pretty expensive, but whats a good drag build, that is reliable and still makes over 80 hp? lol is that possible to be reliable and over 80. all opinions are appreciated. thanks
