Hahah yes I will. If the product is here, it will be worth a lot haha. Na the 5.7 do better on LPG, but maybe I talk about the older 350's, out of the 80s for example. But I don't know that stuff yet. LPG is very cheap here in NL, 60ish cent per liter and 98 is €1,60ish. But will drive motorcycle more to compensate. And upgrading will cost like 800 and deleting 400. Then I will try to sell the parts. Well my LPG guy said he knew about the 5.3 head issues. But he didn't mention which years. I believe since the 2003 flexfuel version they have hardened valves... but not sure mate
My engine ran gasoline untill 220ish km and I just past 300k kilometers. And have a valve fluid system but that one sucks also and no one really believes in that
