5.4 in a Fox?

The biggest issue with the Lightning setup is engine/hood height, you could do a GT500 engine in it without needing a huge hood or having to cut a hole in the hood to fit it.
Agreed. And the GT500 swap would probably be faster. It would be missing a bit of the WOW factor going down the road

Yeah but it would be lighter if you get the aluminum blocked one, be a good sleeper and better upgrades available
Agreed. The biggest issue I have with the 5.4 for most swaps is they make the fox nose heavy

It's the same weight as a big block, so all the guys doing big block swaps have the same weight up front
I've done the BB swap. They handle like crap on the street.

Yeah, no argument there but it does have a serious wow factor when you pop the hood...
Any 4V in a Fox is going to have serious wow factor!
Most non-Modular guys can't tell the difference between a 4V 4.6 and a 4V 5.4.
Agreed. Particularly the old school guys.

I also have dropped a 5.4 DOHC (other than my FOX500), it was carb'd with a sully!! Ended up trading it on a 03 cobra before I got finished but I didn't run into any issues other than hood clearance. I had manual brakes to boot!!
Very nice

It really depends on what intake setup you use and how you setup the whole car, I am hoping with my new intake I could get away from having to have a cowl hood so if I decided to do a sleeper look I could, I have 1/2" k-member spacers to help clear the brake booster... That notch back is super clean and runs very good, I think it's still stock GT500 8.5:1 compression... I hope to have my car running this spring.

Great job guys I'm I'm middle of getting mine in soon, I have hydro boost but not sure if I need to remove sway bar mounts, just had finished smoothing bay don't wanna cut them. But hydro boost looks like it will be impossible to install
The hydroboost really isn't that difficult to install. There are a number of threads on there that will give you step by step instructions and lots of good pics.

I meant to install motor with booster off or on more of a clearance issue, some say best way to install motor form bottom and cut sway bar mounts, I guess I'll find out soon. Lol
More parts to purchase ..

If it is going in from the top (the way I did my last one), fit the hydroboost first to make it a bolt on, then remove it to be out of the way for the engine. Then it is an easy reinstall. I plan to do my 4V (current project) from the bottom, mostly because I have a high ceiling in my garage now and have room to go up as needed. My last project was much fewer mods with a stock fox suspension and a factory sn95 kmember, so the fox swaybar was not a problem. I used Steeda relocation mounts and it fit fine.
