" From: Frank Swygert <farna@xxxxxxx> " " ... I hated to see all those NOS parts dumped, but " you can't blame Chrysler for writing off what was basically non- " moving inventory. They got pennys on the dollar (of retail " value), and some will say they could have sold them, but it would " have taken a lot of time and effort to catalog and sell the " parts. they could've sold them the way they dumped them - job lot, all-or-nothing. i'll bet there are places that would've snapped 'em up for scrap prices and done the cataloging themselves. " I have to disagree on the engine Andrew. It wouldn't be hard to " retrofit the 4.0L with roller lifters, not when the main casting " could be easily changed. The only problem now is getting the " lifters not to rotate. If I had access to the engineering " department I think I could come up with a cost effective way to " do it! Retrofitting an existing casting is a different story, " though it has been done. Need to modify a lifter and cross bar, " but if I had resources to manufacture my own lifters... the block could take a lot of work to get access to the lifters in the gallery, but if they did that i'd've designed it to use la rollers and retain them a similar way. but first i'd want to do a stress analysis on the outer wall of the lifter gallery and see what if any stresses it carries in the engine, or if it's essentially just a protective cover, before i went making holes in it. afaik the only 'modern' straight six that could really easily be converted to roller lifters is the chevy 194/215/230/250 and 292, with those big bolt-on lifter gallery side covers, but it's been out of production for vehicles iirc since '89. it lasted maybe 10 years longer for marine apps; iirc the 153/181 four is still going. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
