A: The later Caddy V8 (including Northstar) uses a 60 degree pattern, same as the 2.8L Chev V6 and AMC 2.5L. (I hear the Chev 2.5L had 2 different bolt patterns) I don't think there is enough room (at the bellhousing) to swap an AMC motor into the BOP TH425 or later Caddy FWD trans. Anyone know if the early AMC 6 cyls were the same pattern as anything else? Took a long time to "nail" down the FACT the early Jeep TH400s were nailhead trannies (I finally did the match up) From: adh@xxxxxxxxxxxxxxxxx (Sandwich Maker) Subject: Re: [AMC-List] rambler hot rod // backwards six To: amc-list@xxxxxxxxxxxx Message-ID: <200610040420.k944KxD13613@xxxxxxxxxxxxxxxxx> " From: farna@xxxxxxx " " 4.1L V-6 (larger version of the 231 -- I wonder if SBC pattern?) they're both buicks, with the b-o-p pattern. some time in the mid '80s, fwd 3.8s started using the little gm pattern that the amc four has, but only in transverse apps afaik. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _________________________________________________________________ Add fun gadgets and colorful themes to express yourself on Windows Live Spaces http://clk.atdmt.com/MSN/go/msnnkwsp0070000001msn/direct/01/?href=http://www.get.live.com/spaces/features _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
