I have a 1997 F150 4X4 with a 4.6L "6" code engine and the 4R70W automatic transmission with 244,000 miles. The trans. was rebuilt at 175K and it fine, the engine is shot, main bearings knocking. I want to swap it to a PI (Performance Improved) engine. Buying a PI engine for a F150 here is like buying gold, upwards of $2000, and they have nearly 200K on them. I can get a 4.6L out of a 2005 Crown Vic with 75K, for $800. I have a few questions about the swap.

If I purchase a PI intake for a F150, will my injectors and rails work it the PI intake?

Will the flywheel from the Crown match up to my 4R70W Torque converter?

Are there any other road blocks that I will run into making this swap?

Thank you all in advance.

We did something like this with my brother n laws 99 model about 2 years ago. I can't member what all we had to do to make t work but I know a fan was one thing we had to change. the crow Vic motor water pump wouldn't accept a clutch fan and a truck water pump would fit in the crown Vic's motor. It seems like I remember the propellers being to big. But anyways we hard to run electric fans on it. I also think we had a small problem with motor mounts. I really can't remember tho it's been some time since. But we are bout to do a motor swap on it again lol that motor slung a rod out the side.
