My builder and good friend is putting one together based on a new Pond block. Along with the original engine components he is using a set of Ford original SOHC aluminum heads. He was still deciding whether or not to use that 7' snake of a cam drive chain or a gear drive for the top end.
I believe he found the engine in the shop of an old Nascar mechanic he does some work for. Last I heard they were going to drop it in in a '68 Galaxie.
