RE: What's going down with my 96..
The npi intake does really suck. That is almost as limiting as the heads. The plenium volume is just so small. This is what I learned on PI heads if you are planning on doing the p&p yourself don't take the entire piece out behind the intake vavle, you can cut it back but don't take it all the way out. You will reduce low swirl and lose some low end torque. Another thing you don't really need to touch the exhaust ports they are big enough and only clean up the intake side some.

RE: What's going down with my 96..
Ok here's the scoop. I just put a brand new replacement manifold on like a year ago before I had plans for the headswap that cost me a pretty penny. It's brand new so there's no sense in getting the new manifold again. Also I'm getting these heads for $100 shipped to my house w/ 72k on them in the best condition they can be with that milage. I've read up a few articles and there are guys who have P&P'd NPI heads and have outflowed PI heads with them. It's going to cost me next to nothing to get these NPI heads cleaned up so it's definatly cheaper for me (a college student on a budget) to do the NPI P&P route.
Alternative Auto is in Mt. Clemens MI and a guy names Lideo owns the shop and does all the tuning there. He's known around the nation for his work and has guys from out of state coming to him to get their cars tuned. I've sat and talked to him quite a few times and this guy knows his ****. He'll be doing the tuning on my car.
I feel I can get decent #'s out of the car with this route. I'm not trying to get this car super fast or anything. It's more about the experience than anything. I'm going to school to get my degree in auto tech and doing this engine work means more to me than making the car faster, it just so happens I'm killing two birds with one stone.
Hey amoosenamedhank, thanks for the pointers on the P&P I'll definatly keep that in mind when I'm doing the work.
I'll keep everyone posted on the situation and the progress of the project. The heads should be shipped out tomarrow and will be in my hands early next week. Then the real work begins.

One more thing...
I'm not positive on the stage 3 cam now, I still need to determine which one will give me the best driveability. Here are the specs on the stage 2 and stage 3 cams.
Stage 2 = Street perf, 3.23-3.55 gears, good torque and hp works with stock computer.
XE268H-14 Dur @.050 230-236 | Lift .500-.500 | LSA 114 | RPM Range 1600-5600.
Applications: 1992-Present Ford Mustang 4.6L & 5.4L SOHC.
Stage 3 = Hot Street Cam 3.55-373 gears, 2000+ stall, computer upgrade, rough idle.
XE274H-14 Dur @.050 236-240 | Lift .500-.500 | LSA 114 | RPM Range 2000-6000.
Applications: 1992-Present Ford Mustang 4.6L & 5.4L SOHC.
What do you guys think? Now looking at it, I think I may be better off with the stage 2. I don't want a totally agressive idle for a daily driver. Also even though I plan on getting the car tuned ASAP after the work is done there's a chance I may need to wait, and with the stage 2 I can get by on the stock computer for awhile. What do you say?

well it depend on what your doing with the car i have stage two comp cams but they are .550 lift and i have a full p.i. head conversion i went with it because under that description i had 3.55 gears 2,00-6,000 seemed about right for my rpm range does pretty good on the highway got in the vid section and you can see how much a comp 274h idles and sound with flow it under Rantheman or here is a link https://mustangforums.com/m_1522771/tm.htm
go down to the 3 and 4th post

Even with stage 2 cams i think you will be able to run mid-low 13's, if you can catch traction i vote high 12's... let us know how it turns out

The only thing is that Muscle Mustangs and Fast Ford's Red Headed Step Child project had very similar work done and even replaced the 200k short block w/ the stock specs and could only squeeze 276rwhp out of it. I can't remember the tourqe #'s off hand either but now that I read that article I'm just shooting for some sort of improvement and not getting my hopes up. We'll see what #'s come forth when the car is done!

PI heads are not NPI heads with a p&p job.
You will not be able to mate up a PI intake to your NPI heads if you do not have adapter plates. If you do, it will still cost you power.
Also, if the alternative auto is the one I am thinking of, isn't it in NY? There have been several people posting about massive problems with this shop.
ALSO, porting 4.6L heads is quite a job. If the guy has not done it before you need to rethink this. It is very easy to screw up a port job on a 4.6 and end up costing yourself alot of power.
good luck.
