Slant 6 HEI

Anyone ever see what the Australians used to do with the Slant 6? They used to take two Hemi heads and gut the alternate ends off, weld them together to firm a single inline 6 head, and bolt it on. They raced them, ran excellent.

WHAT Hemi heads? This is something I'e researched IN DEPTH since I HAVE a 56 331 Hemi out in the shop. There is NOT ONE Hemi head that's even CLOSE to the bore and head bolt spacing of the slant. The closest one is the Dodge 241 Hemi. It has bore spacing of 4.187 and the slant is 4". I'm not saying it cannot be or hasn't been done......I just wanna SEE IT.
