97 f150 swapping a 5.4l to a 5.8 (351)
hey i have a 97 f 150, 36 inch tires w/ 6 inch lift on it, blew the head gasket on the 5.4l and was not pleased with the performance i got from it any way. I bought a 302 i was going to bore out and build up but just came across a 5.8 that came out of a 95 ( i think) computer and all for free, so from what i have read i need a c6 transmission to go behind the 302 or the 5.8 so i am picking that up this weekend. Has anyone done this swap yet? i cant find any threads online about it, which is making me feel like its a bad thing. This truck is my mudding truck and i am looking for as much power and torque as possible, i feel that the 351 is the way to go here, so let me know if anyone has any suggestions, comments or any nay-say's about this project.

I would do a 351W over a 302. However your asking for alot of work to change from a 5.4 to any motor in a windsor family. You would need a new engine trans transfer case for the 5.8L Also you will need new motor mounts and possibly crossmember. I have no idea what kind of electrical nightmares you will come across trying to swap this into the newer style truck as well. In my opinion I would just fix the 5.4 and not get into the headache of trying to swap a pushrod motor into your truck. I agree the 5.8L is a great motor but your looking at a pretty good deal of work here.

460 c6 205 done.
if it's a toy go carbed big block. if it still has to be a driver find another 5.4 and look around for a super charger. any motor swap is going to be a huge pita, so be prepared to spend a lot of time and money on things.
tinian has a 460 in his late model truck, i have no clue about how he did it though. maybe he'll share some rigging knowledge
EDIT: idk if he swapped it yet or not can't remember if he did and is building a second motor or if he didn't swap yet.

If it were me, I'd put a 5.4 back in (and maybe put a supercharger on it) or (if its not much work) a stock supercharged 4.6. BUT the poll says ultimate trail truck.
Trail truck seems to suggest a need for fuel injection so it makes me lean toward the 5.4l again
but he also says he wants lots of power so for simplicity: carbed 460
ULTIMATE trail truck = fuel injected 460 - C6 - 205 - DONE

I think the PI and up 5.4's make more power than a EFI 460 ever did.. in stock form, anyway. 265hp and 380 tq maybe? The stroke, small bore, cam profile, and some other things about the triton's made them have some NUTS down low in the rpm band, they were just always hampered with bad gearing from teh factory in the trans which made them feel like slugs, IMO.

paul, the power ratings are similar between a late model injected 460 and the 5.4's, but the 5.4's make their power up higher in the rpm band and make them seem weak compared to a big block. good motors, just not really a comparable set. 460 ftw!!!!
i talked a lot with guys in the later model sections when i first started posting here on a regular basis.

Did you read what I wrote? They make something like 80% or better peak power by 2k rpm and hold that number up to 5k or so. The 3v's are even better on their tq curve. The mod motors have excellent power bands, but again, were always saddled with poorly geared transmissions IMO. Yes, they can be spun, and like to be spun way up there, they are OHC afterall, but with 3v, VCT, VVT, bla bla T the mod motors had extremely impressive power bands.
What would be a very interesting swap would be one of the new ecoboost motors if you could find one out of a wrecked car, though I wonder if the blocks are different at all from the FWD to RWD configurations. The RWD F150 version doesn't come out for a few months yet. Anyway, 95% peak tq from 1700 rpm I think it is? 420 lb ft electronically limited. You should see the tq curve on these things, it's ridiculous. With a tuner and some breathing work I don't see why those motors couldn't reliably run 550+ tq.

yes i did, and i told you otherwise. get over it. if guys that own and drive triton trucks told me that their old 460 trucks felt stronger lower in the rpms i believe them. numbers are just numbers. real world ability is a whole other ball game. and don't give me that gearing b/s, most newer trucks have better transmission gears and rear end gears are about the same for both, 3.55's and 4.10's. late models have 3.73 as well and i believe maybe a 3.27 option as well.
torque is where it's at.

There were prototypes making ridiculous power at ridiculous displacement levels, but they were dirty and couldn't pass emissions and the fuel economy sucked. The triton truck motors were not all that impressive in 2v form originally. The PI versions were a little better, the 3v v10 was pretty damn good. The 5.4 3v was in a fat pig of a truck in either two options. The 4.6 in the stang was an impressive mill for it's day making 300 and later 315hp in a <30k car was an amazing thing. Ford's choice to go with OHC's is FINALLY starting to pay off with the new 'coyote' motor, churning out a heavily under rated 412 in the stang, and 365 in the f150, it makes the small block cheb motors look like ****in boat anchors. The 6.2, while not quit as impressive as the technology packed 5.0, is also an OHC motor making ridiculous power numbers.
I bet you put a triton motor and a 460 motor (stock, highest power levels available) in the same trucks, with the same gearing, the triton walks all over the 460. (especially a v10 triton) Better yet, put the fruition of all the years of development of the Tritons up against it, either the 5.0 or the 6.2 and see what happens.

well no ****, the highest rated efi 460 was i believe rated at 250 hp, it was more like 27-280 hp but they didn't want to overshadow the soon to be released v10. scj 429's were like 450 hp but also got derated, but that was for insurance b/s, do they count for this test, what about a shotgun 429

NOW WE'RE TALKIN'!!! Put a v10 in that b****!!!!

i could maybe get on board with this idea, but i vaguely remember reading something in a mm&ff that said there was an issue with swapping them, don't recall what it was, but i think it was a computer issue.
if v10's didn't sound like **** i would love them. ever heard a straight piped v10? sounds like a pissed off trombone with a bad reed, horrible
