As far as the 6bt and SVO PLEASE don't do that to a great engine. I have almost 5 yrs experince with SVO/ WVO and Biodiesel, if you do any kind of alt fuel. I highly recommend Biodiesel. From all the data that I have collected it is a proven fact that SVO WILL coke up the insides of the engine, and injectors. It may take 30,000 mi but it will happen. My first (only ) WVO test was an 85 vw golf and after 10,000 miles and about a yr, it had lost a lot of compression and was burning lots of engine oil the only thing left to do was rebuild the engine.
I got a call just this week from a guy that was working on a 92 dodge that had been run on SVO for only 500 miles, it had broken the rotary injection pump and clogged all the injectors.
As far as your conversion goes, I would love to see the pics. Sounds like a great conversion and hope to see it soon.
