Fastest/ most powerful slant six?

Steve Nitti out of the Twin Cities in Minnesota - he has a blown custom methanol and fuel injected six putting out over 525 hp. Its the highest horsepower /6 I've ever seen. A really wicked duster!

He also has a 'like new' 66 baracuda

This thread is worthless without picchhrres LOL
