The AL engine will fit all the Classics! I think you meant American though. After looking at Tom's photos I think the AL engine will fit the 58-63 American with somewhere around 1/2"-1" clearance between the rail and pump/filter. Lucky for you the filter is horizontal instead of vertical like on the iron engine! IIRC there's about a 30 pound savings with the AL block. Everything else is still cast iron, remember! Aluminum could be used with a permanent steel mold (die casting) and cost less to machine, those were the real savings for AMC! The only thing they stated about the weight savings was that the car would turn a lot easier, so you didn't really "need" power steering with it. No real gas savings or anything like that. I doubt anyone was offended that you addressed Tom and I specifically. Others do on occasion! Also, neither of us would be offended if someone else answered the question even though it was directed at us. I certainly jump in if I know the answer if someone specifically asks another person. It's like we're all standing around talking about the same subject and you look to your left while asking a question and I'm standing on your right and know the answer. I'd certainly give the other guy a few seconds to answer, but if it sounded like he was unsure..." excuse me, but I know that answer!". Since there is sometimes days between people reading the list, I don't think it's rude to jump in if you know. The good thing is you're not butting in or cutting anyone off if you do on the list, might be if it were in person! -- 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
