Ford F150 - tired and wore out 4.6 333,000 plus! its time to do a swap

i recently purchased my 98 f150 1/2 with a 4.6 in it the truck frame has 330,000 miles plus and i cant say about the engine and drive line. i sold my GK tiburon GT because the harsh wyoming weather here is not low slung sports cars friendly...
basicly after reading sevral pages of posts i would definaltely like to do some sort of a motor swap, weather it be a 4.6 dohc mustang engine, or a 5.4 triton what ever!! or even build the 4.6 thats in there with a bullet proff motor
also i have all the turbocharger stuff from the tib that i pulled off before i sold it!

parts list are
garret t3 70 trim
OBX deltagate
synapse bov
cx intercooler
AEM FIC
and all the oilines and fitings couplers blah, blah blah

so could the experienced builders and modders chime in and point me in the right direction

threads,forums, or info would be great!

HP goal are 500at the crank or 450 at the wheels what will it take to achieve this!!!!!

thankSS

400HP is bout the maximum with a two valve bottom end, if your goal is 450-500 the cheapest way to get that would be a two valve 4.6 or 5.4 with forged rods and pistons. the crank and block can still handle that. next would be a newer three valve motor with a stout bottom end that would make somewhere in the 600-700 range and still be reliable, after that an aluminator crate motor will pretty much handle in upwards of 1000 ponies at the crank. get a 4R75W trans out of a lightning to bolt to it and you got a pretty stout daily driver that will be reliable.

yeah that does seem logical to get that boat anchor out of the engine bay and swap it out with something better, i wanted to stay with the 4.6 due to the engine being closely matched to a mustang, now i was also under the impression that what can fit on a 4.6 mustang can fit on the truck as well, within reason. i know the heads are different so if i were to due a swap i would have the problems of the electronics not matching.
what engine bolt to the trans.

i was reading about sevral that looked similar,
first choice would be a mercury maurader emgine. 4.6 300+ hp
secondly would be 4.6 out of a police interceptor crown vic
third choice would be a simple mustang engine
last would be an actual 5.4 swap

any one of these would be better than what in there, i understand if i due this swap i would have to change the electronics over,main harness and ecu! secondly how can i get my trans mission to work with these models of ecu! or will that be a problem

im definately not worried about the injection part, AEM FIc can handle that i can get controll of the stock fuel tables and add fuel where ever i would need it! also with this i can gain control of the OEM fuel injectors and up to 18% more fuel and add or take away timing

i was curious i was even able to dump the two valve heads and swap to the dohc 3 valves form the newer mustangs ill use there stock intake and get rid of that goofey a$$ one that in there now. is that an option, i assume that there is no difference between the twos bottom ends its all in the head work, more air due to the valves and better intake and bigger throttlebody, better cams???

can this work!

the three valve mustang motors are single cam, only the four valve motors have dual cams. the trans should bolt up with an adaptor since the mounting locations are similiar for most mod motors, in fact they are even very similiar to older small block ford motors of the 80's. you can definatly swap out 2V heads for 3V or 4V even although to go to the DOHC 4V heads would be counter productive since a 2V bottom end is pretty weak. but with some fitting and a little research on some aftermarket parts a 3V swap is possible, I still think you should just go with a re built junk yard motor. navigators came with 5.4 4V DOHC motors, some forged rods and pistons and you'll be smokin most lightnings.

so where can i find that adaptors. and what problems will i encounter with the electronicsam i using the the ecu from the navi or will i use the 4.6. i assume that ill be using the wiring harness from the navi. and how will the electronics work with the E40d trans that i have in there

Either a 2v 5.4 complete or a 4.6 2v rebuild would be the easiest. If you go 4.6 go stroker crank and rods and bump up to 5.0 litres. No major electronics change that way. Just a custom tune for whatever you build. You can stay with the coil packs pick up a hi perf set and tune away. To make big power either way will have to do an intake manifold swap. Lots of options on 2v heads including the new trick flows. Lots of mod parts for the 4.6 because of the Mustangs.

A good forged bottom end will take 650 to 700 hp. Im making 600 or a little more and have had no problems.

i was thinking about something like this! better flowing heads intake swap to a mustnags intake, a new aggresive cam! and 150 to 200 shoot of nitrous!

You have the right idea with the bottom end. Intake manifold, a good set of heads and cams and it is a nice stout little 5 litre. The nitrous does help with weight of the trucks. I run a 125 and that is lots. Remember to budget for tranny rebuild, converter (these motors rev high and powerband is up around 3500 rpm), gears and a good tune.

If you don't want to go with the nitrous look at building a 5.4 a adding the cubic inches for the torque.

well heres the question to be asked i guess, high compression NA engine or
build it up and boost the hell out of it either twin turbos or a whipple?
are there any good ECU reflash people out there?
where can i get a good trans that can take the abuse?
where can i get a good LSD that has some 4.10s or a good gear ratio?
i friend i work with can rebuild a torgue convertor and get it set up for me!


i kinda wana stay with the 2valve thats in there, just so i dont have any problems with electronics and no one can give a good answer on if 5.4 3 valve would be better for the build, and besides theres more stuf out there for that 4.6

like 1black said if you stay with the 2v you can use all your electronics. if you want to get to 3v or 4v then you need the computer and all that stuff to go with it..then you have to find someone that can properly tune the motor so that it runs right.. a dyno tune is best in this case

im looking at a jet ECU reflasher the performamce based one! im a wasting my time with this? and 130 hp+ gain is alot to boast! some how i doubt that the unit can deliver that would put the stock hp to 350ish only 100hp gain away from my goal of a solid 450 to 500 this is to good to be true! i mean i can undertand if this was a heavly modded engine but its not? or can assume that i can see around 30 in real life gains by reflashing the ECU! am i right!
