antera309 3 Posted October 29, 2005 Report Share Posted October 29, 2005 Stock BHP for the 2.9 is 190 Link to post Share on other sites
ukdub 0 Posted October 29, 2005 Report Share Posted October 29, 2005 If you are getting your 2.8 rebuilt the 2.9 is the natural repair size, just have your block rebored and buy some 2.9 pistons. An instant handy increase in bhp and a rebuilt engine as well. Link to post Share on other sites
