Craft86MJ Posted July 14, 2010 Share Posted July 14, 2010 Hi, I have a 86 MJ with the 2.8 V6 5spd manual trans. I'm in the process of restoring it and was wondering if there are any somewhat easy v8 swaps that would work for my application. I've did searches and couldn't find anything Thanks!

Craft86MJ Posted July 14, 2010 Author Share Posted July 14, 2010 Thanks, what would the best year be for the 3.4L to do the swap... pre 1995? Link to comment Share on other sites More sharing options...
Pete M Posted July 14, 2010 Share Posted July 14, 2010 I don't believe it matters which year of 3.4/3.1 if you're using just the block. are you swapping just the block or the entire wire harness to get the fuel injection? Link to comment Share on other sites More sharing options...
Craft86MJ Posted July 14, 2010 Author Share Posted July 14, 2010 Might try for the fuel injection, not for sure yet just a thought, its gonna be a DD for sure. Link to comment Share on other sites More sharing options...
Pete M Posted July 14, 2010 Share Posted July 14, 2010 you might be able to pick upa whole car for the price of a junkyard motor. then you'd have everything associated with the wiring and can still part out the car and haul off the rest for scrap.

Craft86MJ Posted July 14, 2010 Author Share Posted July 14, 2010 If I was just using the block will the factory intake and carb from the 2.8 work on the 3.4? Link to comment Share on other sites More sharing options...
Pete M Posted July 14, 2010 Share Posted July 14, 2010 yes. block and heads are like 98% the same externally. :thumbsup: see this page: http://www.lunghd.com/Tech_Articles/Pro ... ect_XJ.htm Link to comment Share on other sites More sharing options...
