Going into my 4.6 soon

I think if I was going to start moddin' a 4.6 with 101K miles I would go ahead and go through the block while I was at it. It may run perfect now, but go adding horsepower and possibly a heavy foot and who knows how long it will be before you have to go back into it. Go ahead and build the bottom end now so it can handle the mods you have planned for it.

With 110 on the odometer, it would be wise to rebuild the entire block. In my experience (w/ fleet Crown Vics) 100,000 + miles gets close to the compression ring failure area. It is not to say that you would experience failure, you just run the risk...

Pull and replace or just buy a good used low milage 4.6. In good shape it can handle boost and you may save money on all the labor and trouble involved in rebuilding and old NPI block.
