The 4.0L is significantly longer (by about 10") than the 2.5L. Dad used to own a Premier -- the 2.5L would be tight under that hood! The V-6 is a cylinder (about 5") shorter than the 2.5L four. Look under the hood of an 83-92 Audi 5000, in the later years (90s?) called the 100 and 200. These use an offset radiator due to the length of five cylinder engine. I don't think even that arrangement would work for a 4.0L Premier though. -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://farna.home.att.net/AIM.html (free download available!) ----original message-------------------------------- Date: Thu, 28 Sep 2006 10:14:37 -0700 From: "Rhett Butler" <amc.inline.six@xxxxxxxxx> Are you guys sure? The AMC 2.5 seemed to fit in there just fine. Would it be really all that much trouble, since the Cherokee, Comanche, and Wrangler took both? Again, I have no idea, so it's a legitimate question. I understand that the 4.0 is longer than the 2.5 (and most likely, significantly longer than a 90-degree V6). But again, this is just a pipe dream, anyway. As much as I love AMCs (and believe me, I do), I find myself almost as interested in the cars it built and sold for the company that cannibalized them. If I could find a Medallion in good shape, I'd take it over the Premier. _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
