Why is there an LS1 option in with Mustang engines? Why does everyone insist on comparing them? LS1's are highly overrated, they have shitty rod bolts and they "God-like" cylinder heads are only held down with 4 bolts compared to 11-13 on the Modular. I guess maybe it's because Chevy is SO damn smart.

4.6, 5.0; doesn't matter to me.

4 bolts for the cylinder heads? Are you fuggin kidding me? wow...the what the hell motor was I working on last month? thats 4bolts around each cylinder port there chief. THEY HAVE THE SAME AMOUNT OF HEAD BOLTS/STUDS AS A 5.0. Do your homework before you get on here spout of some BS Misinformation next time. The only motor i have ever worked on that had only 4 head studs...was a SINGLE CYLINDER FUCKING DIRTBIKE. Get Real...

LS-x all day. FUCK the haters.

That's what I meant. Call it a "type-o". Or maybe I wasn't paying much attention to what I was typing. :crazy2:

as everyone stated the rod bolts and pushrods are weak points from the factory. Also the stock valve springs cant be reused if you run a decent cam but all of that is easy to change. Another weak point for many of the aluminum ls motors is that the cylinder walls are usually pretty thin so they cant be bored out much. Also as stated before they have a 4 bolt head pattern which means that when alot of nitrous is used sometimes the heads will push off the block. Also sometimes people get spun bearings, not sure how though. Overall they are very reliable..a buddy of mine has almost 200k on his motor and it still runs like new. I also had 130k on mine before i accidentally blew it up a long time ago, it was my fault because i kept missing gears and overrevving it. They also weren't forged from the factory but then again not many motors are and you can buy forged ls1's for close to nothing nowadays, i picked mine up for 2k which really isn't much at all.

Well, the rod bolts, as previously mentioned, have their limitations. The fact that there are only 4 bolts surrounding each cylinder for head mounting. Beyond that, there might be something less important, but I don't know what it would be. IMO, the design team did a really good job on the engine. Of course, like anything else, there's always room for improvement. Hot rodders and racing are notorious for finding any weak points.

I'll add that the stock pushrods on LS cars tend to be a bit too easy to bend from a slight over-rev. However, that's really not a bad thing as they act sort of like a "fuse" that may save you from piston-valve contact.

Plus, they're easy to change out.

How is that any different that a 5.0 or 4.6? A 5.0 will split up the middle if you even look at it wrong at anything close to 500hp in most cases. The rods in a 4.6 (termi motors excluded) are powdered metal...I'd rather BEND a rod than shatter that powdered metal pos....and terminator motors have been found notorious to for the piston to wall clearance being too tight. As for being able to bore an LS-1 out...you can't bore a 4.6 over .020" or stroker it past 5.0! The valve sping argument is a moot point. Who puts a cam in and doesn't check or replace the valvesprings? You're either a) incompotent or b) not putting in a big enough cam! As for the head bolt arguement...the key phrase there was ALOT of nitrous....not just nitrous will cause the heads to lift. That goes without saying for any motor equipped with head BOLTS from the factory 5.0, 4.6 or otherwise.

Find me one ford motor that you can make 450 rwhp w/o nitrous or boost on and without having to even pull the factory heads off of....

Thats all I'm saying...

I'm not saying that the 4.6 or 5.0 isn't susceptible to any of that. Honestly, I'm just annoyed with the "LSx is God" talk. That's just me though. I don't have any hate towards that particular engine. I'm just a big Ford fan on a Mustang forum :dunno: Sue me. Whatever though. To each his own. Right?
I'm not familiar with every Ford engine ever produced but I'm certain that there is at least 1 that will make 450rwhp without a headswap or FI.

4.6, I always pull for the underdog, and as far as modification the 4.6 is probably the hardest/most expensive to get power from

x2 I'm gonna have intake and exhaust, and I can't even keep up with my friends lt1 with mufflers.

arent you like stock except for a kn?
what do you expect?

I dont except you to keep up with 4 banger altimas

LSx. Every time. No question. More power. More cubic inches. Smaller. Lighter. Better BSFC.

And you run 14's...who you knockin'?

RY and Paul not to start an argument but if yall like the LS series motors so much why do you not have one?

 

[94Pro-5.0]

LSx motors are cool, i just dont like the cars they are put into.

stock for stock, and LSx imo is a better motor, so, stock for stock, i'd take an LSx, but i WOULD NOT put it in my mustang.


If i could build my ford motor (aluminum block ect like chevy) however i wanted and could build a chevy motor however i wanted, i would build my ford motor

so, my answer is LSx

Because I like the way the Mustang looks better. I would fully support any LSx-stang swap.

 

[Petek]

why does everyone have such a hard time accepting the fact that the LS1 is superior to mod motors or the 5.0. if everyone would grow up and accept that there would be no more stupid ls1 vs ford motor argument. okay? move on.

 

[Paul]

Werd.

 

[95 svt cobra]

5.0. i like the idea of being able to work on my engine if it breaks and it not taking 2 weeks to do so

 

[Spooling2Valve]

5.4 4v. or the 6.3 stroked out version.

+1, It's the logical choice. Sorry haters.

B/c when I built this 331, I didn't know any better. When I pop it...the car is NOT going to have a Ford motor in it anymore...don't worry.

any engine you can beat the piss out of and it gets you home is a good engine to me. GM quality is not there any more. Fords is getting better so. thats what I base my personal opinion on. 5.0 good motor can beat the piss out of it and it keeps going same with the 4.6. Every summer I will meet people at car shows and chat with them. they love there ls whatever but they all complain about the poor craftsmanship of the motor. One guy even told me that if his ls1 was built as good as the 5.0 in his work truck he would drive his camaro more.
