I have an 89 F150 4x4 with a 302 EFI and AOD trans. The engine is just about shot in it. I ordered a same year long block out of a crown vic because I wanted a roller engine so I didn't have to worry about the flat tappet issues with the oil. I had to order a steel distributor for the roller engine since the cast iron one that is in the flat tappet engine will damage the roller engine(or so they told me). Everything else I'm planning on using. Correct me if I'm wrong but I believe the fuel injection, intake manifold, valve covers and oil pan should work on the new engine. But not sure about the timing cover or water pump. Is the timing cover and water pump different for a roller? Is there anything else I missed?

 

I don't think anything else is different.

 

X 2 i think everthing will work , the steel cam gear for the roller is correct....Lew

 

So after a few hours researching these 2 engines(yeah I have no life). I found that the timing cover, water pump and intake manifold gasket have a different part number. Although the intake manifold for each engine has the same part number, the gaskets have different numbers. The crown vic is not an HO engine so not sure about this but I will have to look into it some more. The valve cover gaskets, harmonic balancer, exhaust gaskets and oil pan gaskets all have the same numbers even though the oil pan is different for a 4x4.
