You're more or less correct. The water pump and timing cover are thicker on the V-8, so it's more like 5-7" shorter instead of 8-10". But it takes up a lot more room side to side. For the six get a CJ-5 water pump and pulley. 1/2-3/4" between the fan and radiator is normal for the Americans and Gremlins and Hornets too. --------------- Date: Sun, 3 Apr 2011 08:04:42 -0600 From: Lynn Howell<lynnhowlyn@xxxxxxx> Thanks for the confirmation - and other details added by all who responded. One more quick question .... Because I'm struggling with the length of the engine in my specific situation (e.g. the water pump "nose" is much closer to the radiator than I'd like .... it's a long story), my sense is that most any of the AMC V-8's would be 8 to 10 inches shorter than a 258 .... a couple of approx. 4 inch cylinders and a couple of water jackets shorter. Does that make sense. -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://www.amc-mag.com (free download available!) _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
