RE: V8 into 258 humpster

[<mail@xxxxxxxxxxxx>]

You've got the 258, Now, pick up the 4.0L and AW4 out of a 2 wheel drive Jeep. Then throw the 258 Crank and rods in the 4.0L. It's a quick way to 275+ [depending on the overbore you use] cubic inches of AMC based six!
  For a Header, you can use Clifford or any of the 4.0L exhaust manifolds will work. 2000 up 4.0L engine actually come with split cast iron exhaust manifolds. I don't know that anyone has done an install with these in an AMC car yet though. I have a set, but I actually forgot to test them for fit before I put mine back together! So I have them ,but don't know how well they would fit :[
