My '73 J4000 (originally a 360 4bbl truck) came with the nailhead trans and Quadratrac (without the optional low range). The first Previous Owner (WA State Supreme court judge) had a new tcase installed with the low range and O/D kit (which is really just a smaller gear and shorter chain) I added the needed low range shifter (it never had one and the shifter was caked in very old rusty mud that had obviously never been used) I also have a 327 with TH400 ring that may end up in my buddy's '83 Wagoneer with my old TH400 and QT (as I am parting out my J4000 and the 304 is getting a 727/NP208 combo to maybe go into an '85 XJ with upgraded axles) From: Frank Swygert <farna@xxxxxxx> Subject: Re: [Amc-list] fsj 232/th400 [was: AMC Ads] To: msproviero@xxxxxxxxxxx, amc-list@xxxxxxxxxxxx Message-ID: <4696DFCD.2050309@xxxxxxx> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Spro, you didn't miss anything much, just don't understand how the early Jeeps w/AMC engine fitted a TH-400. The AMC TH-400 case didn't come along until around 1972 or 73. It was used through 1969. Prior to that the "universal" model TH-400 (same as the Buick "Nailhead" case/bell -- it was also sold as the universal to other makers because the shallow bell left plenty of room for an adapter -- the old Buick Nailhead had a deep flange on the back of the block) was used with a cast iron adapter ring 1.5"-2" thick. The ring was used mostly with the AMC 327 (65-67 in FSJs), but some Jeep sites report that a similar setup was used with 71-72 AMC V-8s. The 327 has a different bolt pattern than later AMC V-8s, of course. -- Frank Swygert _________________________________________________________________ http://newlivehotmail.com _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
