I wanna do a big block engine swap to my 2002 f150 and im wondering wat size engine i should get. I was thinking the ford big block 460.

 

no point.. the 5.4 makes more power than the 460.. unless u just want the simplicity of a carburated engine.

 

I'd love to do a fuel injected FE swap into a new body style truck. While these mod motors are nice and make good power, I can just work better on a pushrod.

Allright, fine, call me old school.

You can put in any motor you want, just have to fab up your mounts, exhaust, and all the sub systems.

Stick? Auto? Fuel Injected? 4x4? Lots of planning and money will let ya do anything.

Finally, what are your states emissions laws?

im looking fo a big block that puts out about 400 hp

 

Um, thats a negative partner. Remember, there is no replacement for displacement. A 1969 ford 460 block in stock form made 385 horsepower and 500 pounds of Torque. The new ford 5.4 makes 300hp, which pales in comparision.

Now that being said, it would be a large project to undertake and a real biatch to pass emissions, unless you are in a place without emissions. I have the same idea floating in the back of my head, as I have a 68 Continental 460 residing in my garage as we speak.

 

Hmm...are you talking about gross hp or (SAE) net hp? My guess is you are mixing up the two. Forgive me if I judge too quickly. Either way, I do agree there is no replacement for displacement. If you get a good set of GT-40 heads, cam, intake, headers, and crank/mainbearings that can take the pounding, go for it. 400, hell, 500 hp and 500-600lb/ft of torque should easily be within reach of a motor of that displacement. How you bolt it in and what tranny fits is a challenge all by itself.

Good luck!

 

For those of us that have trucks to actually haul things; the torque numbers are most important. I don't have comparative numbers right in front of me, but I know that it takes about half-again as long to get up to cruising speed from a standing start with my empty three-horse slant-load in my '02 than it does in the wife's truck -and it's an '02 dodge

As much as I love my new-to-me Ford; the 5.4 cammer's bottom-end "grunt" has been a disappointment, I'm afraid. Makes me miss the FE in my old '72 all that much more.

 

390-427-428 FE would be a fine choice.
I built many and they make nice power. The torque is unbelieveable.
Nice cam, intake, maybe a set of aluminum heads, headers, and a good old Holley, or Edelbrock 650 or 700 and you have a real beast on your hands.
I think it is a good idea. Let us know if you pursue it...

 

i definatly agree..
however you must find one of these first...:santa:

...zap!

 

More wisdom from Faster.

 

He should just unload his truck and get that Dodge thing. Then maybe have it twin turbo'd by Gale Banks or the like. Should be good for 900hp and like torque numbers. Then have the truck lightened by 1500 pounds. I do not see why a Hot Rod truck should weigh as much as that thing!

 

427, in your dreams (and mine) good 428 bare blocks go for $1000, just the block, 390 are available but that is starting to be mid size engine. a nice 425 - 450 hp build of a 428 or a stroked 390 (430) will cost you $6k minimum (PROBALBY MORE)

the reality is that a stroked 351 to a 408 makes a great motor that is light and powerfull, a stroked 460 to say a 514 or a 522 make even more crazy power. both would be cheaper to build than an FE.
a stoke rebuild 460 with a 429 timing chain and a small rv cam with headers will make an easy 390 hp and 450 ft torque (at the crank)

the real reality is that none of these engine are going in a new f150 unless you have skills, fabricating tools, $$$$ and a lot of time. put a supercharger on it and call it a day.

 

That's all? Keep in mind that the newer trucks are a LOT heavier than you think. I say go all out...put a crate 460 in there, or if you're really wanting some guts, how about a crate 514.

Ok, well maybe not...not all of us can blow $6000+ on a crate engine. I'm a poor redneck arkansas boy....I have to BUILD my own stuff to save money. If all you want is 400 HP, go find an old Lincoln, LTD, or big Mercury (or any truck) and pull the 460 out....put a good intake and 750 or 850 carb on it, headers, and a small cam while you're in there...and 400 HP is a piece of cake. 500 HP is also easy but requires a little more cam, compression, and some massaging to the heads.

Those 460's will make serious power.....easily.

 

1992-1996 - 7.5 L 385 V8, FI, 240 hp umm im correct..
http://en.wikipedia.org/wiki/Ford_F-Series

the 1996 F-250 wit the 460/7.5L made 240-245HP and around 380-400tq....
the new 5.4L makes 300hp and has better fuel economy..

 

Faster, you bring any stock 5.4, 4x4 or not, and we'll hook it up to my uncle's 1997 F-250 460, with only 245 hp and 400 tq, and we'll see who wins. Fuel economy my ***. I want power. Sure the new 5.4 has 300 hp, but can it pull 15K lbs?

But then why go with a 460 if a 4.6 is lighter and can be made to have more power
