i was just kicking thru some old post and found this one, I was wondering if you got this truck? They di run well in lighter trucks, and I have one I want to use in my 1965 1 Ton. of course there is plenty of info on my Webiste about these engine and I have been scanning more this past month to add, whcih is why I was looking at old post about Toro-Flow Diesels. I just posted some Photo of Toro-Flow Trucks on the
6066 GMC Guy FaceBook page. and I'll be adding you pics as well. included here is a pic of a Twin Turbo Toro-Flow and one on a stand at the Brooks Museum.
