" From: Brien <mail@xxxxxxxxxxxx> " " " " " Subject: mail Digest for 7 Apr 2005 in hour 0:00 " " " the other stuff, a 3.1 " or 3.4L would require a balanced flexplate/flywheel. The 2.8L one is " externally balanced till almost the end of the line. " " as i hear it all the 60-deg engines were redesigned to be " neutral-balanced about '87-8, 2.8 included. it continued on to '93 " in " s-10s, and i think this flywheel would be your ticket if you wanted " to replace your manual-trans xj 2.8 with the gm crate 3.4 longblock, " which is only available with a [700r4] flexplate. " " ---------------------------------------------------------------------- " " " Would the Olds 2001 Aurora V6 bolt in ? that's the 'shortstar' [3/4 northstar] right? afaik most/all gm engines since the '80s have the little chevy v6 pattern, so in theory they should bolt in, -but- 1. dunno the flexplate/flywheel situation. 2. starter location. in the northstar it's in the valley between cylinder banks. otoh i've also just learned that as of the mid-'90s -gm- was using -ford- cased t5s! this was in a long, info-packed thread on jeeps-offroad.com started by 'greg55_99'. and isuzu has a converter housing that'll match the gm bolt pattern to the aw4 - though '87-'93? 4-cyl xjs do too. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
