Hero Gallery
Building this engine for a competition is a pressure cooker of an endeavor, and the really remarkable thing about this effort is that it was put together in only 10 days. That took some real hustle from the suppliers, and a near around-the-clock effort on the part of Tom and Brenda Foley of T&B. In the process, there were individuals who went way beyond the call of duty in getting the job done and lending to the success of this entry. We wanted to acknowledge them here:
