5.0 Upgrades

[robz95xj]

my brother is buyin a Lincon Mark VII within the next few weeks, its got a 5.0, we plan on installin headers and full 2.5 dual exsaust with flowmasters, now the question is, what are the best headers out there? i see dynomax headers for 189 and then i see edlebrock for 427, any tips from the 5.0 guys out there?

tell him to trade in his vagina for a 5 speed first. For real though, I don't see how you can go wrong with $200 headers.

full exhaust , intake, under drive pullys, ac delete, 4.10s, is it speed denisty or mass air

[American Psycho]

pretty much all the crap from a 5.0L mustang will work.
IE rearend/trannys/wheels/ all 5.0L engine stuff.

I think they are also the foxbody. never was into the lincoln. im sure someone will correct me.


are they long tube or shorty?
Shorty equal length or unqual?

dynomax is ok. just make sure you get the locking header bolts and retighten them after a few healthy miles.

^Ain't it too big to be based on em? I would they are crown vic based

[American Psycho]

nah. similar to the cougars / thunderbird platform.

i wouldnt go all out with 4.10s unless hes gonna be racing it, just start with some 3.73's everybody says gears are the best mod to do and they aint expensive. couple hundred to buy and get them in stalled if u dont to it urself. theres a bunch of stuff u can find from the junkyard for 5.0 engines and gain performance, like the upper/lower intake manifolds from a late 90's 5.0 explorer are gt40 manifolds. let me find a thread for junkyard parts for ya

im not lookin into gears, maybee a lunchbox locker, were just lookin into bolt on goodies as far as headers jim the dynomax look to be longtube and edlebrocks are shorty's, whats the performance diffrence between the 2?

[American Psycho]

long tubes are for race cars
get a catless h-pipe also

dude gears is the best for a buck mod. get 3.73 and it wont really hurt ya gas milage. get a full exhaust, intake. ac delete , and underdrive pulls. also u could find a cobra intake manifold cheap up there with new throttle body , would be decent gains.

im not gonna have him dump money into a 28 spline 8.8, need for him to get the car first

first dump the low output heads and find a set of H.O heads, or like johnny said, find a scrap exploder and rape the gt40 heads and intake..the car is based on t birds but it's just a longer fox platform and it has slightly better breaks the the stangs.. ditch the 273 gears the automash!t came with for better gears. gears are cheap. cheap headers and an off road h pipe will do the trick, you don't need high buck headers, you won't feel the difference.

[robz95xj]

what year explorers had these gt40 heads? and how strong in the 28 spline 8.8? i know alot of jeep guys running the 31 spline vertions but have no idea about the 28 spline vertions

[Traction Issuez]

if i remember correctly under 98 is gt40, over 98 is gt40 p, you will need different headers.

oh, i have broken everything but my stock diff.
