Only real change was to change the bolt pattern on the frame from small pattern to the big one.  The old one was cut out and a new plate with the correct hole spacing was welded in.  I used a 4620 intake manifold to get an intercooler and the 4520 exhaust manifold.  With those manifolds all the holes in the hood matched up perfect.  The 4520 water pump was used to keep the fan in the same place to work with the fan shroud.  One other small change was I had to go to an electric tach because the engine did not have a manual tach drive.

 There really was not much modification required to make it work.
