hi all

just wondering if anyone had tried to build a Ford GT motor 5.4 supercharged 500+ horse, and put it their cobra

no need to build it , you can buy one from ford racing for only $45k....just the engine. then try to fit that puppy in to most , if not all, replica engine bays. Bill.

Not that I know of, but I'm sure someone has tried. However, our engine guys are finishing our 4.6 DOHC with a stack injection system. We had talked about a 5.4 S/C motor and they can build an engine very similar to the GT for a few less dollars

. These engines (Modular Ford) are dimensionally very large, even bigger than an FE or 429. Fitting them into Cobras can be done, but it is a tight fit. I'll have pictures of the installed motor in a couple of weeks. Are you trying to do a build-up with a 4.6 or 5.4? I read your other post, we have a 500 h.p. 4.6 DOHC / Tremec TKO 600 package, ready to drop in and fire up for $12,900.00. That package is with a carb and special intake. I also have the same package with a full blown stack injection system for $20,100.00. If you need prices on a modular crate or package, give me a call.

I read about someone switching to a Ford GT block in a Ford Lightning.
Ford GT engine block is only $2,795 - but it is machined for a dry sump oil system. It can be remachined for a wet sump.

You may also want to consider a new 5.0L "cammer". It is already complete and you can use aftermarket electronics. The wiring harnesses should be easy to find. I'm pretty sure it is the same block size as the 4.6l 4v just with a stroker set-up.

Our you can find a 4.6L 4V and stroke it to 5.0L yourself. They make big power with Ford Racing FR500 heads/intake/cams and a free flowing exhaust. Probably a lot cheaper than a Ford GT set-up.

The 4.6 DOHC cobra engine is already wider and taller than a FE or 385, as said earlier. However the 5.4 is a taller, wider deck, by roughly an inch. The 4.6 DOHC cobra is an aluminum block and already heavy (from what I find on the enternet about halfway between a 351W and an FE). Not many aluminum block 5.4 were made which is going to put it about another 100 lbs more, if you use a cast iron 5.4 block. Anything can be done, but I'm sure the 5.4 would be harder to fit in a Cobra.

anybody using one of the sean hyland 4.6 engines

There are TWO 5.4's and it appears some of us may be confusing the 5.4 that comes in Ford pickups with the 5.4 that comes in the Ford GT. They may LOOK similiar but they really are quite different.

THATS why the 'real' Ford GT sports car (NOT Mustang) 5.4 is $45K, different crank, different block, dry sump of course, etc.

That sucks, the salesman told me that my 150 had the same 5.4 as the Ford GT - I bought the truck on the spot. Are you sure there different? My truck really gets up and goes and there's somekind of "tank" up front - could be a dry sump?

This is true. Just had it confirmed. Even my engine guys will charge close to that number to duplicate the motor with the correct block and dry sump. Thnig is they can boost the output to 600 h.p.

You can build a "look a like" 5.4 GT from the Lighting motor that puts out around 600 as well for between $25,000 - $30,000

These 5.4 motors seem very expensive for the return when you can go out and get a warmed over 4.6 DOHC with a carb that puts out the same 500 h.p. for about $14,000.

A 'replica' 5.4? Now who would want one of those...

Good one! If you used the OEM production dry sump block would it be "Real" or "Continuation" ?

What I should have said is a 5.4 with the almost same set up and horse power.

You can't go wrong with the "cammer". It's already built to be a flexible alternative - wiring harnesses and elctronics are already done and available

You probably want to read on the 4V Mustang boards for information on Sean Hyland. He is well know in the modular world but so is Al Papitto from Boss 330 racing. People also rave about VTengines.

There is great article in the recent MM&FF Trucks special that covers Lightnings. It is a build up of the 5.4L aluminum block to be put into a Lightning, I think it was Johnny Lightning's truck - fast Lightning guy, ran in the mid-10s at like 133 or similar. Naturally the output was far higher than the Ford GT output, no since in not building it better when you are starting from scratch.

You actually believed a SALESMAN? Basically if they tell you something that doesn't really sound right its not....

Unless,,, Crackers pulling our leg.

I don't believe the 5.4 GT engine will fit the car. I have a blown 4.6 and it is an extremely tight fit. The 5.4 is not only a one inch taller deck, the supercharge package is also taller. On a 4.6 the blower and its top pulley nearly touch the hood.

By the way the the engine is very light. When I started I saw all the same 650# stuff. The real world is different. Aluminum Block 105#, heads complete 65# each, Crank 55# rods & pistons 15#, Dry sump hoses and pan 17#, Whipple blower and manifold 70 or 75# (I forgot). Supercharge it! The blown version of the engine has a torque curve that is flat as a pancake from ~2000 to 6000+, you won't believe its responsiveness. This is one potent engine package.

600 HP in a blown 4.6 is easy. The car's fear factor is staggering! Don't forget to get some driving instruction if you've never handled this power level in a light car. It will bite you in a blink of an eye if you aren't paying attention.

How can you Yanks not know about Sean Hyland.

Go the alloy 4.6 block (99-01) and change the rods and pistons and add a blower. Lighter then the cast iron version and works out cheaper and better hp then buying a brand new 03-04. I haven't blown a hole in the side of my engine yet so don't worry to much about the strength thing. Mind you it has only ever been on an engine dyno.

Over here in Australia we fit the 5.4 Boss engine in Cobras. I have one of these engines in another car and it pumps out over 460rwhp @ just over 8psi.

But just go the 4.6. Parts are cheap and readily available for anyone in the states.

The internet source I saw actually claims that the aluminum block DOHC engine is 20# heavier than the cast iron SOHC engine. I have doubted that since Sean Highland said the aluminum block is 80# lighter than a cast iron block. I just don't see 2 cams, 16 valves and springs, slightly bigger head, and steel crank adding up to that much more weight.

I have a DOHC engine on the stand, but no way to weigh it short of dissassembly. It needs pulled apart anyway. Maybe this will motivate me to get started.
