jimoshel Posted March 5, 2012 Share Posted March 5, 2012 This has been covered a dozen times but I didn't need the info then and search now is only bringing up fuse box swap. What engines are a direct swap for the 2.8? Only interested in the mechanical hook up, block to bell housing. Not worried about the fuel, electrics. I have a lead on a 4.7 Vortec and a bad 2.8 is what brought this up. :dunno: Link to comment Share on other sites More sharing options...
Exgrayxj Posted March 5, 2012 Share Posted March 5, 2012 Jim I have no personal knowledge but I am pretty sure I have seen the 3.4 GM mentioned as a bolt in for the 2.8, and a much better engine. :smart: Link to comment Share on other sites More sharing options...
dasbulliwagen Posted March 5, 2012 Share Posted March 5, 2012 Later Gm 2.8, 3.1, and 3.4 are direct swaps including all accessories. The 60 degree GM bellhousing will also fit 3.8's, I think jeepcomj has done this. There may be other 60 degree engines that would phisically bolt up, but I'm not a GM guy, so I don't know.
