putting a 95 4.0 in place of a 89 motor

Recommended Posts

The ports are 5/8" higher on the HO head so the Renix manifold won't match up right.

You would need to use the renix head on the HO block to use the Renix manifold.


You can use the HO stuff with the Renix wiring but you will have to adapt the Renix TPS to the HO TB,you will also need the HO accelerator cable and change the hosing for the fuel rail.


If you search around there's a bit of information out there on it.
