The 818 street looks ok, but I agree with Paul, doesn't really grab me. The race version looks better, but still not outstanding. The performance is supposed to be very good though.
Road & Track (? I think it was) did a pretty nice article on it.
Tim, looks cool, I'd like to see it. Mark and I talked about them on the way home from Omer's Thursday. Sounds like a lot of fun.
At the Fenton show last year I was talking to a Mustang guy that was getting almost 1,000HP out of a 4-cylinder!
