When I put in my 700 I also put in a big block. I wanted to move the engine forward of the stock location so that I would have a little more clearance for the distributor. I moved my engine mount forward 2 inches. Even with this move forward I still had to redrill the transfer case crossmember back about 1 more inch. Keep in mind that I also changed from a Rockwell TC to a NP205 and I am not sure what the dimensional differences are there. Anyway, I did not have to do anything to the front driveshaft so I lucked out there. Also, moving the engine forward 2" put my motor in the right position to use all of the factory BB stuff (2wd) including the shroud.

As far as exhaust manifolds, I used factory manifolds and yes the passenger side would not fit until I trimmed about 1/8 inch from the top rail of the frame.

Good luck! It is well worth the effort. I love mine.
