I want to install a 400 engine into my 2000 xplorer 250 4x4
anyone ever try this or know of the degree of difficulty
any comments would be appreciated!!!

by the way if I get the swap done I will have a 250 cylinder and head for sale bone stock and low hours and a 250 cyclone jug and head .080 over and head milled .020 as well

 

Direct swap, the 400 engine will bolt right in. The rest of the stuff is a pain in the rump. Like radiator, fan, extra wiring, but you should be able to do it.
Use someone else's 400 to look at while doing swap.
The first one is hard, 2nd and so on get a lot easier.
Good Luck..........

 

what kind of extra wiring??

are the holes for the stock 400 engine mounting there??

what model donor should I look for as far as mounts and stuff go??

I will figure out a custom cooling system probable because I have a wicked custom winch mount I don't want to change

 

someone must have done this conversion even if it is info on a 250 TB will be helpful
