I didn't note the aluminum head! Makes me wonder if the LeMans engine (at least the Nash-Healey version) had the clamp-on exhaust pipe like the standard version or a real manifold. The Carter YF works like the one some of us are familiar with that was used on the L-head, but the big Nash six YF is a SIDE DRAFT carb! The aluminum cover plate doesn't mount the carb, the carb mount is machined into the side of the intake. My assumption is the cover plate is used because that was easier than casting the intake in one piece (with a solid "cover", sort of like a water jacket) at the time. Ford later cast their 144/170/200 six complete in one piece, but that was the 60s vs. 30s casting technology. ----------- Date: Sat, 28 Feb 2009 14:58:41 -0800 From: "Larry R. Daum" <mramc@xxxxxxxxxxx> RE: Nashcan sixes I've checked my reference books and the first time the 234 OHV Ambassador six shows up is 1934 and it was used until 1956 near as I can tell. There was a latter 252 version in the last couple years including a LeMans dual jet fire version using two carter YF carburetors. That was the engine used in the Nash Healey's with an aluminum version of the head. -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://farna.home.att.net/AMC.html (free download available!) _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
