Whats better? LS1 or LT1?

[96 LT1-Z]

LS1's easily outperform LT1's, but that does'nt the LT1 cannot bemade a capable performance. If you don't mind going in to he motor and plan some fairly extensive mods like a stroker o forced induction, i'd say LT1 becaus they are very affordable now. Plus one in only decent condition can still smack around a new Mustang GT. LS1's tough ca be 11 second cars with just bolt-ons. Takea look at the November issue of GM High Tech Performance (on newsstands now). They have an LT1 vs. LS1 drag shootout with cars from both camps modified to varying degrees.

wow u put a 4.10 on ur mustang and it only increased 3-4 tenths off your e.t., mine dropped my camaro to 13.1, from 14.1, 1 full second shaved off my e.t. so either the person who installed urs did a very crap job or its just that its a ford which is likely the answer

When you have an LS1 that runs in the 11s off the lot, then say something.

^^^ Sounds like a Ford mans excuse for losing to every LS1/LT1 Camaro out there. You made a point that means absolutely nothing in the world of speed. Who cares if it is bigger??? It's faster and quicker. That is all that matters. If you are looking for a good displacement/power ratio, buy an S2000. Because 4.6's "run better for their size" doesn't mean jack shit. Just my

LS1 F-bodies are totally badass cars, and have many advantages (besides the motor) over the early 4th generation models - stock for stock that is.

If you're planning on putting any money into this new car once you get it you should ask yourself, "how far do I really want to go?"

The fact is that the LS1 V8 (not a 350 cid by the way actually a bit smaller) simply loves bolt on mods. Throw on a better induction system, LS6 manifold, long tubes/cat back, and some computer tweaks and you'll have a car that would simply humble an LT1 equiped with similar mods.

Go a small step further and get the LS1 "Hot" cam and you'll make believers even out of those rich Cobra boys running the SUPERCHARGED 32 valver!!

Having said that, if you're looking for some serious power as attested in Gripenfelter's entertaining vid clip you could pick up a '93-'97 LT1 F-body for in some cases half the price of a newer '98-'02 LS1 Fcar and with the difference stroke that mother to 383, 396, even 401 cubic inches, port out the heads, cam it up, etc..... That LT1 block is as solid as they come and the spare parts bin is still pretty deep and affordable.

This way of thinking is completely asinine unless you don't give a shit about speed. Bottom line: cubic inches builds speed! Do you have any idea how much MORE horsepower it takes to get the average sized pony car from low 12's down to low 11's???..... about 200. A blower might get you there but then what, eh?

Sure, some little fart econo cars stripped down to the frame with 26+ PSI fed, bottle sucking busy bee engines can get down into the 10's (although this is very RARE), you'll never see any sub 8 second cars running anything less than a 600+ cid big block.

It all boils down to displacement my friend - bore and stroke.

You can ALWAYS make a larger displacement engine displace FASTER, but you CANNOT make a smaller displacement engine displace greater than what it is. Think about it.

Cause that is whats moving the crank!

[pimpmaro]

IMHO, screw the Hot cam. That thing is a peace of junk and not nearly worth the money involved in the install. If you want a man cam, I recommend lookin at Texas Speed and Performance or Futral Motorsports and look at their cams that are runnin somewhere around 230/236 .595/.599 113 lsa (the numbers may be very slightly off here and there). That, a good set of headers and a lid with the LS6 intake puts an LS1 around 400 rwhp on a good tune. Ported heads will show between 420 and 450.

[blue4g2def]

nobody ever compares horsepower to time ratios. There is no handicap. Maybe a hp/weight, but who cares if your mustang is more efficient. Its still slower. Keep sayin to yourself that if your engine was bigger youd beat him. Then go buy a rotary that has 450hp+ on 1.3 liters and rant your same whine. There is no handicap for smaller engines, just suck it up and do your best with what you got.

I'd go for the LS1

Bigger is always better thats why bottle rockets don't make it to the moon.

I came across this comparison and it is the stupidest thing I have ever seen. Trying to work the numbers like this is ludicrous. I also drive a Ford Aspire, with its 1.3 liter engine it puts both the mustang and the camaro to shame. The quick camparo to aspire vs mustang.... 1.3 liter VS 4.6, 79 cc vs 281, with having 72% more engine than the aspire, your quarter mile will be 28% of mine, well that is assuming the mustang is equally the muscle car the aspire is.

I have never tried to time a quarter mile, but I am confident I could get through it in 26 seconds. If you want to debate feel free to raise the number, regardless at that speed the mustang would have to pull a 1/4 mile of 7.28 seconds off the show room floor to keep pace. Inclosing I would like to repeat some of your last comments with slight changes.....
I wasn't here to bash the Mustang 4.6, only to say that it is indeed a tight motor BUT since you are so ingenius , maybe you already know that the old 1996 1.3s run better for their size than a Mustang 4.6. NOw

Before I have a whole bunch of stang people yelling at me.... I am not bashing the mustang here. I am bashing the incorrect usage of numbers and ratios. And I also know I could have made it much more dramatic with a riced up 4 cylinder. But since I own an aspire...and its funnier too.

I always thought that the more horsepower you have the more you have to add to see a substantial improvement. like a 600hp car is not twice as fast as a 300hp car.

[Silencer_Nate]

True...unless you live at the dyno ;-)
But seriously it depends on the car as well...if you have a Z28 stock (about 325 HP) and add a few mods and pump it out to 400 HP, you'll see a slight difference. However, you take somehing much lighter, such as a honda (assume it has mods already to be at 325 HP), and add a few more mods and make it 400 HP, since its lighter, you'd probably see a bigger difference.
Aerodynamics, weight, torque, it all matters so some degree...but what do I know? I haven't been to the tracks in a while, so my worth.

[DarthD]

If you want to compare engines here you go:

LS1 - 350 hp (Underated at 325 in the F Body)
LS6 - 405 hp (Z06)
4.6 - 265 hp (Bullit)
4.632V-320 hp (Cobra)

LS1 346ci = 1.01 hp/ci
LS6 346ci = 1.17 hp/ci
4.6 281ci = 0.94 hp/ci
4.6 32v = 1.14 hp/ci (this engine should have a big advantage over the 16 valve engines)

The GM engines put out more power per cube. Does this make them better?

The Camaro has better fuel economy (even without 6th gear) than the Mustang even though it has a much larger engine and is a heavier car.
Does this make the Camaro better?

One thing is for sure - more power per cubic inch and lower fuel consumption = more efficiency.

I am not biased. They are all great engines and awsome cars. I do not understand how ANYONE that drives a Camaro can HATE a Mustang or the other way around.


Personally, I would get the LS1 over the LT1 as long as money is not an issue. It is a newer, more efficient, more powerful engine. That is why I bought one.
They both have a lot of potential though.

Very Nicely said.. Both Ford and Chevy have their strong points, and I was raised on Ford.. But.. Is there really a point to arguing over this? We are on an automotive forum to help each other and give our opinion not tell our opinion as truth. Camaros are bad ass and Mustangs are bad ass it boils down to alot of different things.. I think overall the LS1 engine is better from all my reading, but hell im not even 16 yet and I dont own a car, but I'm just saying that its pointless to argue when we are suppose to be gaining knowledge from others.. we are all going to have our opinion regardless of what the hell anyone says. Hopefully, I will be the owner of a 4th gen Z28 shortly and my dad is a FORD mechanic does he care to work on chevys or dodges? hell no, his favorite car is are Old Chargers.. Camaros, and Mustangs. BTW anyone know of a good 4th gen Z28 for sale around Memphis?

It really depends what you want to do.

Mod for mod an N/A LS1 will gain more than an N/A LT1 since it is a more efficient motor. The LT1 block is however bullet proof unlike the aluminum LS1. So If your planning on going Forced Induction, get an LT1. It will save you headaches and $ down the road.

That is the stupidest thing I have ever heard.

And my vote would go to the LS1 if you are wanting to do some basic mods. You could get it into the 11's with bolt-ons and a cam. And I'm not being biased, I own an LT1.

The LT1's sound so much better though (that's me being biased).
