Did you guys see this article-reprint in the new edition of British V8 Magazine? "There's Soupability in GM's Aluminum V8's" (from Speed Mechanics magazine, circa 1961.) www dot britishv8.org/Articles/Speed-Mechanics-GM-215-V8.htm (Sorry, but this message board won't let me make that URL into a hyperlink.) Possibly this article may answer a few "What were they thinking?" questions. I think the cross-sectional photos are particularly cool! ----- Incidentally, the rest of this British V8 Magazine issue can be read (FREE!) from here: www dot britishv8.org/British-V8-Current-Issue.htm (41 articles, ~740 photos)
