Hello ThomasH,
Welcome to the DOW.
You asked two category of questions. Everyone so far is responding to your first Gas questions.
On the done-it with a GM 4.3L (V-6) there had been three fellows I recall here on the DOW.
Mike LaRosa; Tom Collins and Jan Axelsson.
MikeL is deceased. He did like his gasified S10 a lot. His topics and results are still retrievable here by the Search stacked-paper top tool.
Tom Collins works can be search up too. I figure if he wants, he will chime in here too with his gasified 4.3L pickup experiences.
Here Is Jan Axelsson project topic:
The current 801 posts on this topic can be intimidating.
Easy. Bottom of his first introduction topic is a blue block tool: “Summarize This Topic”. Then only 100 posts to view and read. And the pictures posts get priority.
Now do some reading. Many will not comment until you’ve done some filling in work. The same caves explored for the tenth-hundredth time get mighty wearisome.
Air mixed fuel gas energy release (burn) rate is affected by at least 10 factors only in-engine, loaded, duplicatable. Forget open air burn results. And flares staring. Throw out octane musings. Use it. Track results.
Burn, hole-a-piston; and you went you far. Ha! I learned to stop pushing-it seeing aluminum spatter on the sparks plugs. Saab V-4 street racing. Cast iron heads and block - so had to be the pistons.
