4v and 3v setups are less prone to detonation under boost largely from having the sparkplug located in the center of the head. All of the blocks, whether iron or aluminum, share the same basic design. There have been some evolutionary changes to the block over the years, but nothing revolutionary. If you are worried about lifting the heads off the deck, just go with a set of ARP head studs....not bolts.

 

Umm...

Not sure where your info came from??? 4.6's hardly ever blow head gaskets...even under boost. IF one did pop a gasket, someone most likely had an EFFED up tune, injector, or other issue that contributed to it.

2V's are however known for tossing plugs with the 2VPI heads on occasion...mostly due to the fact that they are barely held in the head with 4-5 threads for the plug.

Here's a pic of mine after it took place UNDER BOOST...at the 1000ft mark at WOT doing a 1/4 mile run. Most of the time the plug just strips the hole for the sparkplug and guys repair it with an insert.

Here's what it did to the coil:

The Plug:

If you really want a 600-800RWHP 2V motor, you can avoid this issue buy buying some of the new TFS heads as they are designed much better, flow great (even better if ported) and the spark plug holes have more threads. And of course some good blower cams.

E85 is awesome for boost and racing cars, just hope you can get it easily and have sources close by. To get 600-800rwhp on E85, you better be prepared to install one hell of a fuel system since E85 requires MUCH more fuel than good old 93 Octane.



Want an idea on costs? Here's mine:

DSS Super Mod Longblock motor with Polished Ported stage II heads, Crower Camshafts, Forged Pistons/Rods, Cobra Crank, 7QT Canton Pan, Spec Flywheel, McLeod Clutch/Pressure Plate and other little crud= 9000$
Kenne Bell Polished Blower Kit = 6000$
03/04 Cobra Fuel Tank and Pumps= 700$
Siemens Deka 60lb Injectors= $360
Modified FPDM= 100$
Dyno Tune = 230$ *reused chip supplied by Kenne Bell*
TKO600 Tranny = 1800$

I installed all this crap myself.. so NO LABOR COSTS. I did pay some lift time to a friend who's shop I kept the car in for a while. My motor is OVERKILL for my application, it is built to handle 700-800 crank HP...and I only have a little Kenne bell 1.7L blower on it..pumping 430rwhp (about 500-510 crank). It gives me room to grow someday..when my kids are out of the house.

Don't forget you will need some decent 31 spline axles, an aftermarket differential, some good upper/lower control arms and other suspension work so it will hook. Some slicks/drag radials help too. How about some brakes to make it stop better?

Be prepared to blow anywhere from 15000 to 20000$ to get what you are seeking. Can it be done more cheaply?? SURE..there's always a bargain out there.

So.. you need to decide how much $$$ you want to put into all this, because you could easily just save your money and go buy an 03 Cobra and keep a lot more money in the bank. Even an 05-06 3V GT with just a blower will pump 450-500RWP with minimal effort on the stock motor...and they come from the factory with 31 spline axles. You could build a couple quick Fox Body cars for all this money as well.

Good Luck with your moneypit. Hope I didn't depress you too much

thanks for your help sohcv8gt.

I'm used to mustangs becoming money pits, since this is my 8th mustang. I originally wanted a cobra mustang, but for 20 grand for a decent cobra, you could build a much better car with a gt and the money you save.

The information I got about the 2v 4.6 mustang blowing head gaskets was from an article in the June 09 Muscle Mustangs and Fast Fords magazine titled "Power Struggle"

 

Problem one don't read car magazines they are full of bull####.

I have never heard of a 2v blowing a headgasket unless it was detonating. It will not take $20k to build 600rwhp. I built my 700rwhp 2v for $15k including rearend, suspension and exterior looks stuff. BTW I ran 23lbs of boost with no headgasket problems.

 

newer 2v heads have 8 threads in the sparkplug holes. My 04 has 8 thread heads, these don't blow plugs.

 

ARC.. any idea what year they started that?? It was into the romeo years..but I always thought it was after 2002?? I thought Ford started it on the Lightnings because they were popping plugs like popcorn?


BEGIZZLE... Notice OX's blower is a Novi 2000. It's a great blower kit with the available intercooler that flows a lot of CFM for the money..and it can get you to the HP range you seek. I've installed a few of them as well as many KB and Vortech kits and for centrifugals..I personally feel it's one of the best kits out there. I've even had an S-Trim on my own car at one point. If I had to do it all over again from the start...a Novi 2000 would be in the plan. I'd do a turbo kit if I didn't have to deal with friggin emissions.

The big-bore, wet-sleeve, stroker engine that Bob was running is suspected to be the cause.

According to this the head gasket issue wasn't because it was a 2v. These guys pretty much have you covered

 

Thanks for the help guys.

Oxstang, would you mind sharing your car setup.

 

Patriot stage 3 heads
CMS stage 3 blower cams
Forged shortblock
TFS intake
Novi 2000 on 23lbs

2004 is the only year for either the 2V or 4V PI heads being designed for a full head spark plug that I know of. The NPI DOHC, cobra R, and GT500 heads all are full head spark plug designs as well. The only other one I know of is the SVO head.

Ford did this in response to the known problems with blowing plugs out of the 2V and to head off warranty claims in the terminators before they blew out their plugs. 2003 terminators and Mach 1 engines still have just 4 threads.

While the 4 thread head plug blow outs can occur even on naturally aspirated engines, I have never even heard of a plug being blown out of a fully threaded head on the 4.6

 

2004 is the only year for either the 2V or 4V PI heads being designed for a full head spark plug that I know of.

I could have sworn the lightnings did this before 04. I am thinking 02 or 03, and I thought the stangs were the same. Anyone care to confirm?

 

BTW I've got around $6k in my built engine and supporting mods for over 600 at the wheels. But I assembled my own engine...so my costs are just the price of parts. So if you can do your own work you'll save BIG time. And yea no worries on popping headgaskets of these mod motors. Stock headgaskets with ARP studs have proven to 26lbs of boost.

 

Does anyone have pictures of the intercooler setup that comes with the NOVI 2000 kit? Where would be the best place to buy that kit from?

 

The paxton intercooler is huge and expensive. Not worth the $1000+ it cost. I paid $280 for my intercooler w/piping. I just made my own piping. Flowed great and I had extremely low IATs.

 

maybe nick will chime in... He def knows. I'm not 100% because my car is an 04 lol.

 

Mine too haha.

 

Hello,

Here's one below that I found:

One thing you should know about the Novi 2000 kit is see the big honkin blower in the pic above? The intake tube attaches to that to suck air in. Well that tube BARELY fits between the blower and the factory radiator. I've done installs of this blower on a car where the customer wanted a BIG aftermarket radiator and the blower tube WOULD NOT go on the blower without smacking the hood because the aftermarket radiator was too big and in the way. I think it was a fluidyne. The customer chose to run an 03/04 Cobra radiator instead. Of course something could have been fabbed up. This was the simplest solution..and the 03/04 Cobra radiator was cheaper so it saved them a little $$$. So.. just giving you a heads up to watch this area for clearance.

Another pic of one. Notice how the inlet tube is riding UP over the radiator.

My car is an 04'...but it came with late 03' heads on my car so I was still sporting the 4 threads per plug crap. So it was definetly a 04' thing for the Romeo's atleast...

 

I found on wikipedia that 03 was the change for the lightning http://en.wikipedia.org/wiki/Ford_Lightning

I also searched around on google and found a couple forums mention it was the 03 lightning heads that got the redesign. Here's a couple links:

http://www.nloc.net/vbforum/gen-2-lightnings/202969-spark-plug-threads-2003-lightning.html

http://www.svtperformance.com/forums/2nd-generation-22/286576-spark-plug-threads.html

It looks like the Lightnings did this before the mustangs. Glad I got an 04 mustang!

 

Must just be lucky with my 02.

 

Very nice car oxstang.

 

Ox..

Looks great. I noticed the feed tube for the blower looks different than the last Novi 2000 I did (a few years ago).. Any clearance problems with that now with an aftermarket radiator? Just curious if they changed the design..

Sound of your specs seems like it’s built for a lot higher then your stated crank 1000+ easy don’t know what rods pistons but I would think Higher then that
