I'll try again!!! 5.4 (mod, no 331 pushrod strokers)

[brianj5600]

and there are mod motor cars in the 6's

And it weighs over 3000 lbs and runs a 28x10.5 tire?

I would love to see one of these in a old mustang:

The cammer is back!

As for the actual swap, I would think the major problems you will have are:

1)Engine fitment-should be fixed with an aftermarket front clip, may need a hole in the hood...
2)Electronic- ignition, transmission, Kar Kraft should be able to help you out in this department etc.
3)Transmission- i guess it depends on what you want

It won't be an easy swap, you won't have the fastest car when you're done, but you will have a reliable, solid motor, and something that is a little more unique than most guys. I say do it, take lots of pictures, and keep us informed!

The new chevy motors resemble Fords more than chevys

Mod motor weigh between 440 and 600 lbs, depending upon head/block material.

The new corvette small block makes 500 horses, but it also displaces 427 cubic inches, or 7.0 litres. IMHO, the Chevy pushrod motors are nearing the end of their usefulness, whereas the new Ford motors are still in the early stages of developement.

not to be an ass but do you guys think before you write? Ford has more cams and superchargers to get where GM goes with 1 cam and half the valves. Less parts = less cost = less to go wrong = less to fix......................

I don't know about him, but I was comparing the Chevy's to the pushrod Fords. As for the older Chevy small block, did you know that the Ford FE big block dist hold down clamp also works with a Chevy distributor? I recently had to tear down a 96 Chevy to change the intake gaskets. My kid lost the dist. hold down, so i tried one of the half dozen I have from 390's. It fit and worked perfectly.

1. Show me a car in racing that uses strut suspension that does not require stock type set up. The reason you won't see one is it is not as good as sla.
2. Have you seen anything on the new LS7? 500 N/A HP. Only 50 less than a Ford GT 5.4. That means with about 8lbs of boost, you get close to 800 hp. If you are not impressed with the new line of GM engines you are either in denial or don't know anything about them. Oh, and N/A capability is directly tied to forced induction capability.
If you look in the new Hot Rod magazine there is a T/A that broke into the 7's with a new gen GM motor. My guess is that would take well over 800hp for a street looking true 10.5 car. Ya, it has a blower, but I'm guessing the 600 or 800 hp mod motors had forced induction as well.

What a heavily modified motor for drag racing will produce in terms of horsepower or numbers has nothing to do with the Ford GT engine. There are plenty of Pro 5.0 cars producing substantailly more hp than the Ford GT and the numbers you quoted for the TA, but those engine combinations would not work in a daily driven street vehicle.

Reply from 65up2d8:
A million thanks for understanding what I am saying. This engine does not produce the "balls to the wall" power I could get from a stroker 351 windsor, perhaps. However, I'd rather have a near death experience than to put a Chevy engine in the car!!!!

The point that you comprehend is the potential in this engine. It is smooth, refined, and driveable even as a 500 hp production package. Before the anticipated floods of posts come rolling in about the driveability of Windsor based engines also, trust me, you're preaching to the choir. My 1968 302 with Holley throttle body injection has been absolutely unbelievable in terms of dependability and power!! I'm just ready to take the next step.

The engine that you have brought to my attention through this thread is unbelievable, however. Its a beautiful piece that I would love to shoehorn between the shock towers of a vintage Stang, but I really want port injection and don't want the hood clearance issues the engine would cause. Hopefully a port injection version of that engine will be offered at a later time. I really appreciate your understanding of what I am lookin for though.

(P.S. I really screwed the pooch on this reply with regard to posting the original quote; a little improvisation was necessary)

 

[unluckyengineer]

haha but you know driving my car home from buying it it felt like I was driving a boat, and diving into corners like it was my job. So I will take the extrae room that the MII setup gives you and I am sure the performance improvement will be marked. So for me as a guy who will never take my car road racing it works good.

 

[00redGT]

I've been thinking of doing this for some time and I'm putting '00 GT up for sale this week, so I can get a classic and do something like this. I'm in no big hurry, so I'll be doing a lot of research over the next year or two before I jump in.

Good luck to you and keep us informed. I'll be watching and reading.

Oh, that 5.4 is pretty tall...it might be better to get an 03-04 cobra crate for similar power. Swap the pulley on it and you'll be really cookin'

Thanks!

I drove a 4V-4.6 for over 9 years (97 Cobra) and currently own a 3V-5.4 (F150 Lariat) and a 3V-4.6 (2005 GT). The mod motors are great for a daily driver, they are quiet, relaible, and make decent power in stock trim which is something you cannot necessarily say about the 260/289/302/5.0/351s/FEs/385s. But for use in a classic these motors will require major surgery just to get them to fit, they are freaking HUGE! And after you finish carving your classic into peices you'll end up with as much weight and less or equal power. For less money you can have a smaller/lighter engine that makes more power and wont require you to cut up your car.

Putting a mod motor into your classic sounds to me like nothing more than a lot of expense, headache, and irrepairable damage to your classic for what amounts to nothing but the ability to say "I did it", but that is just my opinion.

Dave Stribling at www.dvsrestorations.com is the "mod motor in a vintage Mustang" expert. Ping him and he will help you out. He has kits, project cars, the works, extremely helpful as well.

 

[reenmachine]

Coincidentally, I was just on the phone with a vendor and he was telling me about a customer of his who put a re-worked Navigator 5.4 4V engine in a '69 Mustang. He said it is a beast!

 

[Sicarius428]

The 5.4 is a massive engine. Bigger than a 428. You may need to switch to a coil over suspension and cut the shock towers out... which won't be a bad thing realy since you want to modernize your suspension. With the blower I doubt it will fit under the stock hood either So you may need to do something creative with that too.
