For the /6 folks

Did they ever update what became of the one that blew the head gasket? I haven't seen it if they have.

Not that I'm aware of, & now that MT TV & associated are defunct, no telling what'll become of it.
Keep an eye on Dulcich’s you tube channel. I spoke with him at the beach party a few days ago about that engine and he has it fixed and it will be going back on his own personal dyno and in to his 68 dart. All of which he will post videos about.
