The ULTIMATE Coyote vs. LS3 thread.

[Jean Ralphio]

So you're comparing a stock 412hp 5.0 to a 480hp "Hot Cam" LS3? The stock LS3 puts out 430hp.

if he's using a GM hot cam...the 5.0 could be equipped with a Whipple from FRPP

Yeah, that was my point when saying that the 5.0 doesn't make much less power considering what GM offers from the factory with its LS3. 376 c.i. and a decent sized cam and good flowing heads. Only 68 hp more? Not impressive. I guess we could compare the 430hp version too.

True. But we are comparing what the factory offers.

 

[Yaj Yak]

But back to the point... a 4.8 or 5.3 is nowhere near a 5.0 in stock shape. Back to the LS3.

compare apples to apples here though... a 4.8 or 5.3 is LEAPS AND BOUNDS above annnnnnny made of glass 2v out there from a modding stand point...

I agree.

Ford swingers would lose in that debate.

About the only good things 2V's are good for are burning oil and lasting 400k miles

 

[CrunkMaro]

cheaper to mod an ls1 IMO.
its a great garage mechanic motor
valve covers come off in <15 minutes
intake comes off in <30 minutes
heads come off in <1 hour
Cam swap done in <6 hours

on an ls3 you can do a heads/cam package and put down 500ish at the wheels, still drive it daily and still get 25+mpg on the highway.

you can build a 450rwhp 'ls3' for less than 3k including the block.


sure the coyote motor is good news, its a great technical advancement and should make car guys (regardless of team) happy that we are progressing vs going backwards.

but the cost of those things are still skyhigh IMO.

i'd rather piece together a full exhaust for 300 bucks.

I think early LS motors have them beat in oil burning as well lol

if not they do in the sounding like a diesel category when started cold (gotta love piston slappppin)

This.

 

[CrunkMaro]

98s have a bad pcv system
and piston slap issues.
and go thru a quart-1.5 quarts every oil change. lol


back to the ls3

 

[Primalzer]

There is no other engine out there that will be able to beat an LS series motor for the size, weight, power, price, and packaging. It really is a great motor. If you give the Coyote time to age well, parts will become more plentiful and cheaper much the same way the LS has.

 

[Yaj Yak]

ls motors in newer body mustangs are hilariously small looking.

Some specs on Ford power plants:

vs the LS3:

 

[willizm]

Both new 5.0 and ls3 are good platforms. Be glad it's not like the modular 4.6 all over again, The only one that was worth a damn were in the termi's IMO. I don't think there is much to argue about the new stuff we have. Both are solid in their own right.

 

[C.Evans]

For the record, I have a brand new "hot cammed" LS3 crate engine sitting in my garage.

 

[Eagle]

I think that both platforms are VERY capable. The LS has been around longer and proven itself more and has a FAR more significant aftermarket following simply by virtue of being around longer.

The coyote platform will have had the same benefits of time as the LS in 10 years. THEN we'll know which really is better.

Right now, for stock, I think the coyote is superior. For mods though, its still LS all the way.

The LSX motors were a clean sheet design for 97, the Coyote is based on the Modular motor family that has been around since 92.

Either way, I'm amazed to not see this thread going to hell

 

[Eagle]

The coyote also comes with forged rods, stock. Just FYI.

Wish the #8 cyl wasn't prone to cracking though.

I thought that was just because of bad/overly aggressive tunes? Is it actually a design flaw?

What's the deal with that?

 

[Yaj Yak]

additionally though... the ls blocks can be built up. the coyotes can't... which is almost a moot point because its not really necessary... but if you have something go caput on the coyote block with that new sprayed in design... dont you have to get a new one? can't you not "fix" em?

whereas an LS block can be re-sleeved or bored or whatever...
