They are niether ford, dodge, or chevy by my understanding. But totaly custom all alluminum blocks designed loosly on the old hemi pattern. Their are no cooling passages in these blocks just one big chunk of machined aluminum, any cooling passages would take strength away and running the fuel them do that would be a possibly deadly combonation.

Weather say dodge ford or chevy on the side it dosent mean much. Not one single part on these cars is the same as what you get in your avearge mustang cavilier or any other production car or truck.
