The general consensous is that the rods will let go over 450 hp. Boost is a different issue. I know people (on this board even) who ran 8lb lowers safely on a stock block. But, looking to it, anything much over a 6lb lower will bring you over 450hp.

dam zac that sucks that the Rods let go at 450. lol Considering thats where your at now with barly any mods!!! I dont understand why this 5.4 can be such a shitty motor compared to the 4.6 of the cobra Someone at ford should have done there work a little better :argue:

 

[ILLINI-SVT]

We didn't get the forged rods like the 4.6s did. They cheaped out on us that way. Otherwise it's not a bad build.

 

[Boost12]

How are the pistons on the lighting motor?? And also what about crank??

 

[ILLINI-SVT]

No problems. Both are forged. Crank is supposedly good to 1000 hp.

ohh cool cool. Yea im just woundering because of my friend zac. Hes looking to do some kind of build to his truck during the winter but doesent really wanna risk blowing shit if theres too much power....

 

[LSX7]

yeah thanks alot i figured rods and pistons were in order to do this right.... but the crank is ok though... nice.... well idk i have a eight pound lower on now.... but idk winter should be intreasting for sure hmmmmmmm...... :cool2:

 

[LSX7]

ALL I WANT FOR X MASS IS FORGED RODS AND PISTONS NICE TONE TO THAT YOU THINK LOL WHERE IS THE BEST PLACE TO LOOK FOR A SET ????
:headbang: :cool2:

8lber is a lot. You better watch your A/Fs real close or you'll be looking for a new block as well.

One theory on running that much boost safely involves making sure the beast breathes as openly as it can - meaning a ported blower, long tubes, and high flow cats. Other than that, the occasional prayer that your rods hold together won't hurt. You're right at the danger point.

A couple of people here have nice built engines. May be a couple will chime in for you. Other than that, you should show up and chat at a get together, otherwise a discussion like what you are looking for could take hundreds of posts and cost millions of lives.

go to johny lightnings website. theres a rebuild kit for 1100 or something like that. brings the power ability to 700 i think. if your gonna go with a shortblock, high priced go with sean hyland motorsports or johny lightning his isnt to highly priced either. FYI your trans and fuel need to be uprgraded around much past 500hp as well

 

[LSX7]

i have a valve body in the trans now but its needs more i think all in all this will be a fun winter with a broke lil kid name zac but yeah there is a place righ in st. charles where im gonna get my motor done at im going there tomorrow so i let you know on that but other wise im just gonna get rods and pistons but now port on a blower im thinking whipple if i can get the green.... but most likley not but well see starting a new job is always fun.... I NEED A SUGAR MOMMA LOL

make sure the engine builder knows what he is doing! and have fun trying to find a whipple for a lightning, I think there is maybe 2 in existance right now and u better get that suger momma cause lightnings get expensive to build real fast!!!!! :lmao:

 

[PearlBlue L]

the stock valve springs cant take on a kb or whipple at like 18psi... too much boost pushing on them and they wont seat all the way down

so after that do you need new valve springs and valves or what????? idk this winter should be fun if my money tree in my back yard get a lil bigger with that miracal grow............. :laughing2

you would want to talk to an engine builder about that. i had mine replaced when i got ported heads put in and stage 2 cams

yeah this winter is gonna e fucking sick :headbang:

 

[DirtyElbierto]

hp wise, about 450
Boost= its all in the tune, although its pointless to go to above 16lbs on the stock eaton, the heat kills it and you start to get diminishing returns
