I have an 03 F-150 with a bad 4.6 W engine, timing chain failed, took out the left head intake valves and guides and put some nasty dings in the pistons.
I have local access to an engine out of an 08 Crown Vic. 4.6 W. Any reason I can't put my intake manifold on there and drop that motor into my truck?
Thanks,
Lyle

 

All your parts will need to be swapped onto the new block and then it will work just fine, trust me I know!
