Gen 3 wasn't on his list of engines he wants to use. Lot's of guys aren't comfortable with Gen 3. I love the engine. It looks like the most beautiful combustion chamber in 2V history. But we (the old guys) don't have 40 years of experience with a Gen 3 like we do with the other engines. If a Gen 3 doesn't start there's no way I could ever figure out the EFI/electronics/COP etc.
