Would u think it would be right to swap an ls motor into a ford gt?

[redmach2K3]

I went through the swap and will be posting dyno videos in about a month after the motor is broken in. People dont want to just throw prochargers on 4.6 cars anymore or 03/04 swaps, they are around every corner. I am one of TWO 5.4 DOHC Turbo Guys in Kansas City and the ONLY one with a 5.4 Sullivan Intake manifold. It is kinda nice to know that you have done something that no one else has. It is all a matter of oppinion. We are going for 900+ hp we are running a 76MM Precision HP GTS Billet Wheel Turbo on the 5.4 I think we can get there. If anyone has questions about the swap feel free to pm me. I have gone through the whole **** thing. Everyone needs to stop saying you can make this power with that.

to the OP, do what you want.

With what?

[redmach2K3]

5.4 DOHC, or that it is cheaper to make power with other motors. Everyone is entitiled to their oppinion. Do what YOU want to do. The 5.4 isnt cheap but its awesome.

Everyones got buttholes and they all stink....but here's mine.....

First thing to think about is power and torque level that you're looking to make.

Second is are you a NA kind of guy, or does a blower intrique you? I used to be an all NA kind of person, but then I decided a blower would be nice. Thats the way I'll eventually go.

If you can make the power you want (from #1) with a blower (and #2 says your ok by it) you'd be wasting a lot of time swapping.

If you want to stay NA (and everyone thinks different about that) and you can't get to the power from #1 with the 4.6, the 5.4 is a good alternative.

If you simply want something different then what everyone else has and want more power, I'd go with one of the other ideas out there (personally, non GM if it were mine). I'd think new 5.0 in the Mach would be pretty nice. You could sell both engines and upgrade to the 5.0, have the DOHC, and make plenty more power than what you'd see out of the 5.4.

If it's a thought, of I have the 5.4 available, so why not? I don't think the benifits would be worth it. Unless the benifits were the weekend time you enjoyed spending working on the car and drinking beer with those that help.

[Machy uno]

To everyone else who is bashing one idea or the other..... really? Since when did when become a communist country where we do whatever we're told? This is supposed to be a forum of people who are interested in cars and help each other out. Most have Mach 1's but not all. Do we run them off for their 'ideas?' Get off your high horse and let people do what they want. Don't like it? Come up with the money yourself to do it your way. Would I personally put a GM motor in a ford? No, but without GM, the camaro, and the ls motors we wouldn't have the mach. The DOHC came out to compete. It all breeds competition and everyone gets a better product. If money was no option and you simpley wanted the BEST car for your particular sport, you'd have a car that had numerous different parts from numerous different manufactures on it. As to the NA, some prefer to stay NA. Maybe it's a second toy car and they already have one. Maybe it's more excitement. Maybe it's even more of a challenge to come out swinging with a 500 rwhp car that doens't have need for a pressure gage.

To those that are being scolded or laughed at for there ideas....don't worry about it. Little girls will be little girls and theres not much we can do to keep them from getting their panty's in a wad....

Still wont be faster than an srt8 charger on 22's ....

hahahaha ICWUTUDIDTHERE. This 5.4 will demolish that charger and he'll ask what kind of supercharger I got and I'll say "what supercharger?"

I'd be willing to bet the barn that Charger's pussy owner wouldn't line up against my Mach 1 with a hand full of bolt ons. He says his car has run faster than mine in the 1/8th but a timeslip has never surfaced to prove it. Even though he has claimed to have stacks of timeslips.

I've been tossing the idea of doing something similar to this.

[jjm525]

Anyone ever wonder what the pushrod 302/351 would be today if it had been developed instead of the mods? I love my 4.6 but its really a complicated bugger and friggin huge.

I see the 302 in my buddies 89 and I'd love to have all that room to work around the heads/headers.

Is a iron block 302 with aluminum heads lighter than the dohc?

[jbrad88]

John Colletti made a comment about how the modular engines make the pushrods windsors look like the small blocks made the flathead.

To make 420fwhp out of a pushrod 302 that was street able and would pass emissions is a battle Ford could not win. We have the modulars because they are far superior engines for what Ford needs them to be. Horsepower per liter, emissions, fuel economy etc....

Chevrolet has done amazing stuff with the ls engines. Perhaps if Ford had worked on the 351 more but the decision to go modular was the right one.

No one loves pushrod windsors more than me, but the modular's do make them look like a flathead...

[jjm525]

Well, GM has managed some pretty great stuff with pushrods, all legal & pretty powerful/effecient and they are more complex than the old SB but pretty simple compared to the mods IMO.

Makes me wonder where they (Ford pushrod V8s) might be with 20 more years of R&D. Less moving parts, lighter, smaller which we know with these DOHCers would be a blessing.

[jbrad88]

That's really what the modulars have done, which is get power out of less.
specifically cubes...

make no mistake, I know they COULD have done it, but GM did it with Cubes...not a pushrod 302...If ford had wanted to develop the pushrod engines it would have had to be with the 351.

and Yes. GM has done amazing things with their smallblock..no doubt.

To the answer on the original topic...

Build the 4.6 imho. sell that 5.4 and take those funds and build. I can tell you that driving my friends @ 600rwhp terminator did not leave me wanting more horsepower. he is also building a 5.1 stroker for his Mach. that one with fr500 intake and the right camming should be a naturally aspirated beast...

[NeverEnuff]

4.6 FTW. 5.4 would be cool. If you had an alum block, and longtubes, and a good intake. But for all that is custom. 4.6 is bolt on readily available...and you can make 400rwhp on stock cubes pretty easy...just the right parts.
