You'd be better off using a non pi 4.6 with pi heads on it , c&c port/bowl/valve job , long 4 into 1 headers and a 125 HP kit of voodoo juice.

My cousin put one of these in a 1972 F100 with the 4r75w trans and it runs good, it does have a carb manifold and full Msd control set up but still stock long block

[@ragintaurusmusclemercury7023]

I have a 5.4L Triton from a F-150 in my Grand Marquis. All I did was freshen it up and added some cams. It makes 350 whp. I am very happy with it.

[@RadDadisRad]

I like the mod motor. I installed a vortech supercharger on my 2012 5.4 3V expedition. Side note, a supercharged expedition turns heads at Pikes Peak when everyone hears that blow off valve spitting out boost when idling down the mountain.

[@kevinkirk4285]

Wow! Great idea for a swap. I'm totally with you for oddball engine swaps. I'm looking forward to seeing how this goes. BTW, I don't think you can do it. LOL Just kidding, I know you can. Gauntlet thrown. I dare you to pull this off! I have my own oddball swap project and my friends and neighbors think I am nuts. I'm doing a 1983 Nissan Patrol with a 1995 Gen II LT-1 from an Impala with a TH400/NP205 twin stick transfer case on 1-ton axles (D60 front and 14 bolt rear) with links and coil-overs. Possibly the only one like it in the world. Dare to be different!

[@misterbulger]

I was comparing measurements with other smallblocks and the 4.6 is bigger in dimensions than most small blocks out there, so you should have a good amount of room to work with... it is very long and very wide. That being said, I am swapping a Mustang 2 K member and independent front suspension into an 87 Chevy Sprint (1500lb Geo Metro daddy,) The car will only be around 2000lbs with a small block in it and I think the suspension will be way too stiff, so maybe a heavier big block is what's needed to make it ride right! You sir get a subscribe. I like the way you think and the way you got me thinking.

[@nahimibrahim107]

I had no idea you had a KZbin channel. I never missed any of your episodes when you were on Powernation and tonight one of your videos popped up in my feed and I said Holy smokes....that's LT!!!!! Loved this video and hope you choose option 2. Looking forward to seeing this build. New subscriber bud!

[@LawrenceTolman]

thanks for stopping by! And thanks for watching both there and now here!

[@juanf4739]

I always wanted to do this swap. It’s more bolt in than any other out there using factory parts . Boosted 5.4 make incredible power using stock parts. Stock crank easily handles over 1000hp. The heads flow good and have so much potential.

[@GIGABACHI]

Golf Course Applause for not going with another me too LSx, Coyote, Hemi, etc . . . I wasn't expecting an exotic 4v variation but that's nice too. 🙂👍

[@torchthe4v]

finally some love for the 4v dohc! i would definitely at least try to rebuild the whole motor or at least refresh it up, boss 302 rods are great and don’t break the bank, definitely get the head cooling mod as well.

[@joshuaelizabethfoster6276]

Honestly had this very build in my mind for a 2000s thunderbird. The Ford GT top end on the navigator bottom was my build idea. Power to wight is spot on for a five seat chassis. Thought it could be a perfect sleeper. At least 500hp and decent mph, with no inspection issues(smog). Then my son was born our fourth, so a third row became a necessity. We lucked out and ended up with a bush estate secret service yukon xl 8.1, huge and drinks like a fish but always starts and never gets stuck in maine snow lolol. How LT is planning to punch the 500-550hp to 900 I'll love to watch as the GT with the 5.4 didn't get all that much power. Of course the Ford GT is way lighter and ment for 200mph+ LaMans racing (24 hours+straight depending on individual race). So max power is is not end goal with the GT, control is, therefore lighter with less power. At any rate always wondered how it would pull next to a big block once properly built. Happy to watch, Good luck.

[@Bynx_McFyden]

dude i love the ford mod motors, i really appreciate you building one.

[@austinbass5503]

My favorite modern mustang too! And my favorite GM engine is also the 8.1 496 ci vortec w the Allison trans i had in my 2001 crew cab 4x4 short bed GMC SLE, but mine had a vinyl floorboard and cloth seats someone ordered it that way from the factory down to the color which was the silverish grey color whatever color it was it was my fav truck so far that I’ve owned and I sunk it once drained the motor over night ran thicker oil through the engine to flush it and filled it back up w 10w-30 and it crunk right up didn’t take plugs or anything out just held it and played with the throttle till it cleared out drove it for almost 2 more years and no other changes except having to put a different throttle body on it cuz it siezed shut from being sunk 3 months prior so it’d just go in & out of reduced engine power and finally I took it in had it looked at and that’s literally all that was wrong! Toughest motor that I’ve owned and it would run like a mf I out ran newer body style half ton chevys fords etc. only thing that got me was a newer 5.0! And all I had was a CAI and true duals cats back necked down to 2.5 at the back bed all the way out the back tucked and almost turned to the side almost 90d them but it was the best sounding truck ever lol

[@David-zm4df]

Almost finished putting one of these in my 06. Your making life a hell of a lot easier skipping the headers... what a nightmare that was. Good luck

[@Deadvous]

Love seeing this, I’ve been researching doing this swap for the last couple months, only difference is I was looking at going NA with high compression and big choppy cams. Definitely going to follow to see what else I can learn about this process 👍

[@JadXtreme]

When I was building my 6.0 formy G8. My machine shop was telling me about the motor he does the heads for this other speed shop local. The speed shop had a 5.8 V8 from a F250 and sleeved it to get it down to 5.4 liters. It was running twins and made I think 1500 horsepower or more. This was roughly 5 years ago

[@randomdude4669]

I'm amazed how much love the ve commodore/g8 gets still

[@dom_not_torretotedesco5707]

Love this!!!! So glad to see people still out thier building mod motors especially someone with your following 🤙🏼 gonna be so dope and probably inspire some people to go “old school” on thier builds

[@klyneis]

This looks awesome! I've watched some of your LS stuff, but I'm subbing because of this build! I would like to build another newedge Mustang (already have an 04 Cobra in the garage) but I've been going back and forth on if I should do a 5.4 4v with an Aussie intake or a Coyote. This will be cool to see.

[@LawrenceTolman]

Thanks for the sub, and hope you enjoy the mustang content! I just got my Aussie intake today, and it looks pretty amazing!

[@johngz3413]

Build it, de-stroke it with a set of con rods for the 4.6, the. You can spin it up more and throw lots of boost at it.

[@Bwhizz-un1jh]

Those 4v 4.6/5.4 Motors Sound Amazing! Ide put some Bad Axx Headers Exhaust, Cam & Supercharge it.Terminator 5.4 But thats my opinion & an idea ive had For a while now. Nice project you Have!

[@DennisDavis-i6t]

I think you might be wrong on the stock horsepower output of the Ford 5.4 32valve. The stock 5.4 truck engine, single overhead came is 336 HP. The stock 5.4 32valve double overhead cam is 400HP. Not sure where you got your numbers. A stock Chevy 5.3 truck motor is 295 HP. The Ford generates more HP due to the overhead cam setup.

[@adampinczesgarageandfabric9930]

I was thinking more of a parts bin special 5.4L 4v but the navigator engine is easier being complete, when you can find them. gonna be a cool project, I like it.

[@abnpthfdr2934]

Option 2 sounds awesome, but it's definitely NOT a budget build option; for a budget build you'd have to go with option one. With that said, I would think you'd want to open up that engine and see how everything looks in there... and while it's opened up you'll start looking at things and changing things here and there and it'll turn into "Option 1.5" Can't wait to see you do your magic on the Stang and that Ford engine.

[@rainbowbunchie8237]

Option 2 sounds like a BLAST. I'm finally coming into my own as an adult, making friends, making ways to work on projects. These videos inspire me to do my own projects.

[@Hammerback0]

Excited for this build LT, thanks for taking us along!

[@LawrenceTolman]

thanks for watching it!

[@Jmauer]

Thank you, mod motor stuff is getting hard to find now days and it’s underrated.

[@marc-henricerar4170]

Great direction to go. Can’t wait to see how much power you go for in this build.

[@twizz420]

I wanted to do this swap in my 2010 CVPI, but I ended up getting a better job and just sold it and bought a 2014 GT-CS. Can't wait to see how it turns out!

[@jackmagnium6115]

option 2 because you need to upgrade the motor before beating on it. last thing you want is to blow it before it has a chance to stretch its legs. better to be safe than sorry. as for the 5.4L(the one i know is a DOHC or a quad cam.) from what i know it shares the engine block with the Gt and GT cobra along with the 5.2 trinity(the shelby GT500KR engine in the 2008 mustang). its possible you could swap the bottom end for the same one out of the engine of the same block(pistons, rods,) its already got a forged crankshaft like you said so i expect minimal difficulty being its an economy version of the modular family

[@bubbadw60]

I shoved one of these in an 02 f150 I had. Was a fun swap! The intake manifold is something crazy to behold in a truck.

[@motorlife5239]

make sure u replace the Tentioners with cast metal tentioners for your cam chains and guides and upgrade the oil pump to a higher volume oil pump

[@hotflashfoto]

I like the idea of slapping it in there just to be sure that everything bolts up, just as proof of concept. It'll allow you to feel how it drives with that weight on the front and decide if you need front springs or can motor safely with what you have. You'll also be able to hear and feel the engine and possibly detect any mechanical issues early, or determine that it can be run as-is for now. But I also like the idea of a complete tear-down just because that's how CDO works. If you've forgotten, CDO is OCD alphabetized. ;>)

[@jpriller5105]

I used AJE Racing's K member to get a 1 inch drop to clear the brake booster. By changing just the plates it can adapt to almost any engine. Also the 5.4 piston sits .120 in the hole. I'd get a zero deck piston to keep the wristpin out of the oil control ring while giving you alot of crown thickness for boost. Diamond makes a self stock zero deck 5.4 piston that gives about a 9.3:1 compression ratio. If you want to use any of the 03-04 Cobra stuff in between the heads like crossover pipe, the 5.4 is an 1.625 wider. Also if you ever need to change the crank, use a super cobra jet crank. Tested to 1500rwhp.

[@donuthole7236]

CP's are the ultimate pistons for a mod motor. Avoid coating of any kind just run the bare aluminum

[@Worldsonfire101]

Cool video. That engine in whole job. You should do some small job on the the channel. I bet you have viewers nearby with everything already purchased sitting in their garage. Example tune ups, aftermarket ground effects, lips, spoilers, paint, chairs, super chargers, lowering kits, body kits, hoods & hood scoops, functional scoops, muffler kits, etc. This way you quick videos & a lot of content

[@Worldsonfire101]

I myself always some aftermarket stuff, badges, grills, accessories, wheels, tires, seats, etc.. & take 6 months to a year to get around to it.. & so do a lot of people. It’s easy free content if you get your community to bring in cars locally.

[@brunobalestra]

Very cool! Used to watch you on Powernation and your show was my favorite. So glad to have found your channel, LT! May I suggest you swap a Ford V10 into a Town Car or Crown Vic next?

[@jasonmccoy6052]

Build it but build with stock components if budget. Obviously like stock 03-04 cobra pistons. Some lightning rods. Put in 98 cobra intake cams. The Navi cams are actually better exhaust cams. Like f500 cams. And the exhaust ports are designed differently from other C heads. More similar to fr500 heads. Cobra pistons. Lightning rods. New timing set. 98 intake cams. Degreed Navi exhaust cams. Boost and let it eat.

[@donaldspeck9212]

Awesome 👌 5.4 Have all of your internals WPC treated. You are the MAN

[@LawrenceTolman]

Thanks 👍

[@Oldsoldiersays]

Ford GT cams, get your heads ported by foxlake or kaase. Hogan no longer sells the sheetmetal intakes I used but the boss 260 is great. 78/76 should make 800hp @ 15-18lbs.
