more ??s on a 32v in a fox
- Thread starter bz393
- Start date
95+ Continentals had the 4.6L DOHC too, but they were FWD and the block is different and cannot be used in a RWD application.
You are limited to
93-98 Mark 8
96+ Cobra
Lincoln Aviators
Mercury Marauders
03-04 Mach 1's
The teksid blocks only came in the 96-98 Cobra and the 93-98 Mark 8

Get a complete 5.4L out of a Navigator along with the wiring harness and ECU, or get a Sullivan or Aussie intake, cobra heads, cams and a carb and make some serious power. A lower mileage 5.4L can be had relatively cheaply if you search junkyards. If you're willing to tackle a 32v 4.6L swap, why not go for broke and get the displacement and torque of a 5.4L for the same effort?? AJE makes a K-member and motor mounts specifically for the swap.

edit: if you do get the 5.4L make sure you take the stock exhaust manifolds, because no header on the planet aside from a custom one will fit on a 5.4L in a fox bay, you'll probably want a forged rotating assembly with a cobra crank too if you plan on spinning it up high or producing over 500 HP. Hydroboost will also be an issue.

What's the weight of a 5.4L vs 4.6L?
If i ever go 4.6L, i figured a Teksid block 4.6L would be the lightest setup possible of the mod more series

From everything I've heard/read the weight difference is pretty negligible between the two, especially with the tubular K and aluminum top end. It's similar to the debate between 351W based motor and a 302 based setup. You can split hairs all day over a few pounds, but at the end of the day the power and torque gained more than makes up for the weight difference.
The 5.4 is Iron. A physically larger block made out of a heavier metal would be more then a "few" pounds. More like a 60+ lb difference
EDIT: Looks to be a 115lb difference

Are you taking into account the fact that, after the swap, the motor will be moving around a 3000 pound (or lighter if it's stripped) Fox instead of a 5000(?) pound Navigator? Some guys have reported a 75 pound difference between (stock) 302 and 351Ws, but would you rather have a 410W or a 347? AGAIN, a matter of taste, both are awesome. I think the potential of the 5.4L makes up for the weight difference, but that's just an opinion.
Kenne Bell or Whipple anyone?Anything can be built to be fast, it's a matter of taste. I just think the 5.4L foxes are beyond BADASS.
Remember this??? SVT where you at dawg?
I'm more concerned with keeping the car from being nose-heavy and trying to get close to 50/50 than overall weight.
I just figure a AL 4.6L, tbular k-member, manual steering, no a/c and a glass hood might do a pretty good job of cutting down the weight in front vs an all iron 5.4L.
Granted a 302 with AL heads might be just as light.
Another factor is the HUGE hood required to clear a 5.4L

Have you guys ever seen a 5.4L wedged into a fox with EFI and a Boss 290 intake (Australian)? It might change your tune... 
But any mod motor in a fox is awesome, so go for it either way!

1991notch, yeah the 5.4 has a bad ass factor to it but either engine will be a weight increase over a 302. With the 4.6 you will only add 15 lbs +/- and with a 5.4 it will be 130 lbs +/- and thats just too much on a Fox. If it was just for power then save yourself ALLOT of money/time/headaches and throw a 408 in there and make more power then the 5.4 can do N/A.
With a Teksid 4V 4.6 you can get as much as 470 fly wheel hp N/A and if you used forged pistons and rods with a turbo or S/C you can have over 750 rwhp (1200 with a good TT setup) and be way more drivable then its push rod counter part for quite a bit cheaper.
You figure to push a push rod that far you need a good block which would cost more then a complete used 4.6 Teksid. Then the push rod needs heads and an intake as well where the 4.6 came with all you need. The "B" heads flow a ridiculous amount and don't even need a port job for big numbers.
Figure $600 for the engine, $1200 for the stroker kit with forged pistons and rods, $1000 for cams and machine work and you are in it under $3000 and will have around 450 hp.
Now I bet you can prolly hit that with a 351 and nice heads for the same amount but the Teksid will rev to the moon and be lighter PLUS you can safely add another 600 HP to that with your power adder of choice.
It will get better mileage and be more reliable plus have excellent street manners. It would idle so smooth that nobody would have a clue whats hiding under the STOCK HOOD.
Excellent sleeper!

Not entirely correct. 99 and 01 cobra also had teksid blocks (the teksid block was produced unitl 99) although most 01s had WAP blocks. What you are looking for is square casting marks in the intake valley vs diamond shaped marks in the WAP blocks. BTW, WAP blocks will easily hold 600-700hp.

Yup...that's my buddies dad's car. 32V 5.4L Navi motor. Hand made intake.
Anyways....your best 32V to use would be 96-04 Cobra motors. They came in a Mustang, so you can use all the newer Mustang throttle cables, cruise control stuff etc. I used all that stuff in my notch when I did my 4.6L swap.
You will need a tubular fox K-frame for modular engines. You can save $$$ by using a 96-04 K-frame....but it's not a direct bolt in. You must modify the rear tabs that bolt to the frame rails under the car. The track width is wider in SN95 cars, so you must obong the holes sideways. The tabs are also longer on SN95 cars, so you must trim some off in order to get it to bolt up to the FOX frame rails. Then, you must elonggate the holes forward since you cut part of them off.
