Fire ring the heads, girdle the bottom end. You want to use 504 jugs, they have more iron to them. Make sure everything is balanced, and if it were me, I'd look into counter balancing the crank. I don't know if there's a difference between the gas and diesel cranks for those, I wonder if the diesel crank is heavier, you may look at using one of those. I know of a guy who was running a 4 cylinder LLSS on alcohol. Go to and search out Eric Pruitt. He could help you.
