I know of a car in my area that has a 400 inch Chevy full on Sprint Car motor with the dry sump and mechanical piss and dribble injection. Like Guitar says, its no dog! It has a loose converter and 5.67 gears. Its streetable in my eyes and it gets driven out on the street. It makes 800 hp at 9k but down low it makes say 400 at 4k more than a lot of our so called street motors. It lays rubber on command and is an absolute animal! Practical? Not really. Everyones idea of streetability is different. I say try it and you'll be a hero, also its not hard to convert a alcohol motor to gas, you just have to run good gas.
