yes it will work, and it will have about 10 more hp, because it will raise the compression a little more then a pi motor

it will work however you will also need to use the timing cover from the 2000 engine, as well as a few other pieces. It isnt that hard to pull the motor and change the rod bearings, I just finished that myself. And I also have a 2000 motor just like you.

why do you need to use the old timing cover? They are the same, if Im not mistaken. You just need new timing cover bolts.

On both my PI headswaps, I just used the timing cover that came on the npi motor. You need to use the PI coolant tube and water pump nipple off the old motor too.

we swapped timing covers because the coil packs on the 98 didnt have anywhere to bolt onto for the 00 motor. as well as the harmonic balancer pulley is larger and we wanted to make sure it sat flush with the front of the motor so no oil leaked out.....

damn im drunk, i hope that made sense

Why is it these engines tend to spit out rod bearings anyway? Seems like that is the most common failure for a 4.6 by FAR.

I've killed a rod bearing in my 2.3, but it makes more than 2hp per cube so you can't be too shocked about that.

What about the flywheel? I beleive the 96 is a 8 bolt flywheel vs. the 6 bolt in the 2000 block?

the 2000 windsors are 8 bolt, the 96 SOHC will be a 6 bolt. My 2000 motor came with the flywheel, as will many used motors. I have a billet 6 bolt laying around leftover from my first motor if you need it ill get rid of it cheap. PM me if interested.

Just a theory but a few of the modulars I've seen with spun rod bearings were low on oil. For years there was arguments on the boards on how many quarts to use, which dipsticks were correct, what oil to use as some state 5w30 and others 5w20. Low oil level though just seems to be the killer from what I've seen, not just for rod bearings but also for cam journals as well. Not saying this guy did that but it seems to be a contributing factor in a bunch of them.

When you think about it though the 4.6 really is a great engine for longevity. Go through a junkyard and look at the crown vics and you see them with 200-250k miles on them, taxi cabs with 300-400k miles on them. Vehicles with lots of use, regular maintainance that last a very long time. I had 113k of the roughest miles a 4.6 could have and the cylinders looked brand new.

You are very right about the 4.6 lasting well as a service engine. It is amazing some of the miles that the police cars and taxi's accumulate. If it is an oil level issue as you stated, then it would be more critical at high rpms. On an OHC engine, it is very possible for the oil to collect in the heads and valve covers at higher rpms, leaving the oil pan nearly empty. After all, they are pumping a lot of oil up there for the valvetrain and it may simply not drain down fast enough, starving the oil pump. Because it is more likely to happen at high rpms where oil flow and pressure are the highest, it would tend to hurt the high performance people the most, while lower rpm service engines wouldn't be as effected.

I know I'm guilty of letting the oil level get low too. I've been completely off the dipstick more than once and had to add 2 quarts to get it on the dipstick. So far so good with 149k miles, but I also have an npi engine and there is no point in reving over 5,000rpm.

i did run it a little low on oil. so if i change the rod bearings will it b ok. the oil level is staying good and the oil pressure is still really good. should i do this myself or if not where is a good place to get it done.

if you didn't run it a whole lot after it spun, then you should be able to get away with only changing the rod bearings...but change them all. And put some clevite bearings in, it will be worth it. Also remove the main bearings just to make sure they werent damaged.
