There is a website listed in the small print in the lower left corner on the first page in Bob's post, www.1spec.net which is not found. A google search for 1spec comes up with nothing but what is interesting is the street address for 1spec listed is the same as M&M Competition Engines in Franklin, IN. but there is no mention of 1spec on M&M's website. https://mmcompetitionengines.com/
