The Hot Rod article (issue May 2012) has a picture of a cast iron turbo exhaust manifold (Chevy I-6), with the following description:
"Turbo Chevy straight-sixes were a factory option down in Brazil. Sissell has a supply of these cast-iron Brazilian exhaust manifolds, as used by Howland in his sedan."
No Mr. Marlan Davis, factory Chevy turbo never happened in Brazil! Check your sources…
