We have used the same mechanics for my whole life and even prior to me being a twinkle in dad's eye both he and my grandfather used them.

They have been in the ski race scene so can build anything over 1000hp if needed, but also know how to setup a nice neat streetable donk.
They are Ford specialists, own mustangs themselves and although my come across as a little rough around the edges they do really REALLY know how to build a good engine and are bloody good blokes, however, you will have to pay accordingly...
I'd rather pay good $ knowing I'll have a good car.
