" From: "Jim Blair" <carnuck@xxxxxxxxxxx> " " 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) both the iron puke and buick 3.8 were changed to 60* pattern, from sbc and b-o-p respectively, in the mid '80s. the caddy 4.1/4.5/4.9 and -olds- northstar were designed with the 60*. " 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. i'm surprised. the th425 took caddy 500s and olds 455s, and the olds 350 on the later transaxle is basically a low-deck 455 block. ________________________________________________________________________ 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://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
