So the oil pump went out on my 4.6 and basically I didnt catch it until it was to late. I was looking at the MMR 5.4 Short Block and HPS 5.4 Intake. Reason being is the 5.4 is priced the same as the 4.6 short block.
Downside is I want to use my NPI heads (going to port them) I know PI heads are better but I believe the NPI heads can be reworked to flow as good as Ported PI heads.
How tight of a fit is the engine? Are there hood clearance issues? Will I have to change my mid pipe and shorty headers? What needs to be done to the computer?

just build the 4.6... the only way i could see the 5.4 being benifical is if you plan to go all motor... which you should just go pushrod for lol the 5.4 will see a bit more torque but i think the general consenus is its just not worth it. AmoosenamedHank always answers these threads lol.
i do belive you will need a new hood due to clearence issues.

depends I think its worth it in respect to how much the 4.6 already costs. But everything about it is about the same, except a new K member is pretty much required and that will help with clearance issues, the new intakes make it easier to try and retain a stock hood or a small cowl

TRADE MY Mach 1 HOOD + scoop set up for easy GT install (attached, no intake system necessary, unless you want it) for a COWL hood and maybe STOCK + CASH (but probably not). The hood is painted silver, in great shape, does need a color sand, but thats no biggie. Would prefer a swap for a silver one, but will consider many options. Need to trade due to changed plan on this car. RTP/Greensboro/Charlotte
The swap may not be worth it if you already have a running engine. But if you're looking at a situation where you have nothing, and you can start fresh with either a 5.4 or a 4.6, I really don't think it's that out of the picture.
The swap is easy, especially if you use the HPS intake.... I would advice against using the NPI heads because you will need to either by the intake adapters to fun a PI intake(what the HPS intake is) to NPI heads. Or you're going to have to RTV the **** out of it and hope it doesn't leak.
PI heads are cheap, just pick yourself up a pair.
A k member isn't a must but it sure makes everything a lot easier. You'll have to either run shorty headers or custom long tubes. I hear the HPS intake, you will clear a stock hood.
I was looking at the HPS intake, and the local salvage yard has a 2002 5.4 with 65,000 miles on its out of an explorer. I pulled the engine today and pulled the heads off and the block is absolutely garbage. It has some real deep gouges in the cylinder bores and an .040 or .060 overbore wont cut it so a new block is in order.

I went to the salvage yard this morning. The engine was still in the vehicle and the vehicle turned out to be a an expedition with VIN L so its the 5.4 and it has 64,873 on it and it sounded like it ran pretty good, no ticks or anything. I asked if all of the accessories came with it and they did so I went ahead and bought it. They wanted me to take the transmission for an additional $200 but I told them too keep it. I also ordered a K-member from PA Racing. When I install the engine I will take the time to fabricate a single turbo system.

240 cfm v. 160cfm... and once ported 320 cfm v. 235 cfm... thats why
but the 4v head argument goes for 4.6's also... PIs just plain suck

I would have rather gone with a 4v but the price was right on the 5.4 2v, and I am going to have some machine work done to the engine. I thought a 2v would be easier since my GT is a 2v and it will keep the computer happy since there is a lot more involved with a 4v, however if anyone knows anyone selling a pair of 4v heads I would be interested. I am planning on bolting up a single turbo to it.
