I have access to a 6.2 diesel that I was going to put in my 59 Fleetside 4WD. Have opted to hold off for now. I will be following this thread.
In the meanwhile, I have purchased a GMC Savana 1 ton cargo van with the 6.5TD. I too intend to run waste veg oil in a separate 40 gal. tank with the heaters,heated fuel lines,etc. Am considering which conversion package to get. Will be installing over the summer so it will be ready come Sept. for my 87 mile daily commute.
