So you think you know Chrysler Hemi history? . . .
. . . well, this was a revelation for me. Yup, an aluminum hemi head for the Dodge flathead six. Ca '48 - '49. Wouldn't this make for the coolest rod powertrain ever? Drooling, Art ...
Cool! Didn't know about that engine!

I refer you to the definitive article on the subject, written by yours truly in a former lifetime, when I was known as ExcelMathMike. Cazalea Siren in Glendale ...
Believe it or not, Ben [log-in: BDLJ] posted a photo . . .
