If done right, then they can look pretty cool. But I have seen some hack jobs in my day. Plus, I'm not a fan of someone cutting the hood on a highly desired Mopar. Use a 318 or slant 6 car. Like I saw at a show last month, a stock 440 six pack 70 challenger. The owner was a guy who thought big blower were cool, pulled the sick pack and threw on a blower and cut the stock hood. It almost made me loose it on sight.
