have seen mostly just photos on the web.thinking it would be a big engine(read really nasty 500 plus cubes) to reap the benifits...

When i start my car to me it sounds nasty lol Mopar revving to go. But i was curious ,it is somewhat different. I don't know if it takes out alot of guess work when tuning or not.
