The engine will bolt in, you can use your existing ECM and either the new intake and exhaust manifolds or your old ones, The new trans is a short tail shaft model (4x4) so you'll have to locate a long tail shaft (2x4) to bolt on the trans. Isnt your existing trans is a 700R4? The TH400 is a 3 speed trans so you'll lose a gear.
