I've been out in a few cossied escorts and they are simply awesome, I even started to collect bits and pieces to build one myself (admittedly this was partly becuase everyone else was doing it at the time ).
However, I decided that whilst the cossie'd escorts are amazing and thrilling to drive, it just wasn't the same as a pinto with a big set of webers snarling for air at full chat - its unmistakable and brings a smile to my face each time I hear it. Whilst it may be heavy, old and have a dated design, for me this is what makes them old skool - its all part of that old skool ford package. If I wanted a modern engine with more power I'd buy a modern car - not molest it into my osf. With all these modern engines being fitted I cant help but look at them and view it as 50% old skool and 50% modern. It's not genuinely old skool anymore imho.
I suppose what I'm saying is that the car with the more modern engine is a better car for it, but it doesn't quite have the soul of an old skool ford with the original engines that made us appreciate them in the first place.
All imho of course
