5.0 VS US

They can rev a lot higher than a stock LS3 and most shift at 7K if bone stock. Once modded, they can rev to 8K and still make power all the way to that RPM. Not to mention, the MT-82 in 5th gear is a 1:1 and the stock gears in a track pack model for example, are 3.73 which also help quite a bit.

There is only about a 100-150LB difference between an SS and the 5.0 and they make nearly identical power.

A great comparison is a full bolt-on 5.0 vs a cammed SS. Both are very much capable of bottom 11's with the right driver, despite the Camaro making upwards of nearly 500 RWHP with a cam, good tune and fuel.

Again, once you mod, it is anyone's race. Stock for stock, the edge goes to the 5.0 either from a dig or a roll.

The 6th gens, however, are a different story. More power, bit less weight than the previous 5th gen and are very well built cars. The 2018 5.0 may stand a better chance, but, the 6th Gen SS is most likely a tick faster with equal drivers.

See, that's getting to my point. You mentioned "despite the Camaro making upwards of nearly 500 rwhp with a cam..." In what little I have seen, a typical bolt on 5.0 (11-14) you can expect 430-440sh? Correct? If that's the case, why does the SS not have more of an advantage? You could say weight was a penalty but it also has a significant more torque. The 5.0's seem to defy the horsepower dis-advantage when it comes to moderate bolt-ons. I just want to know why? It seems to have something to do with the sustained upper rpm power??

It goes to the 5.0 if they have 3.73 gears but could be a drivers race if they don't "stock for stock"... Of course I only speak of experience with my old 05 CTS-V (from a roll) so I'm not sure how it stacks up to my Camaro... yet...

FYI - 3.73 gears are a factory option on track pack models and can be added to factory orders as a separate gear option.

The 5.0's love high RPM's. They are designed to be high revving motors.

The 4V heads flow extremely well and don't require modification, even in F/I applications.

Your everyday bolt-on 5.0 if dialed in with 93 octane can make about 450 RWHP on a Mustang dyno. My 5.0 put down 443 on 93 with knock through the mid-range, but, still pulled strong. I should have ran 100+ octane or higher and I'm certain the car would have made close to 460 RWHP or more.

Again, there is a bit of a weight difference, and the SS's are not geared like a 5.0, especially the L99's. The LS3, that is a different story.

From a technical stand point, I for one, can't explain why there is an advantage, just that it is proven the 5.0 has one mod for mod, stock for stock. Weight could be it, who knows. I do know, either car can run amazing when dialed in correctly.

Lighter weight and better gears do quite a bit on the street.

Changing to the 4.10 didn't add any power to my car, but it's a whole lot easier to be in the right gear for whatever roll races I come across now.

from my experience it goes like this

1st - Auto 5.0
2nd - Tie between the two M6's all drivers race
3rd - Auto SS

This is all in stock form. no bolt on's no boost and this is for S197 coyote's 2011-2014 with less weight and solid rears

There is a video on youtube of a 5.0 coyote S197 vs a LS3 swapped S197. The LS3 car destroyed the coyote car, both basic boltons. LS3 is a torque power house.

This is all specifically drag racing style comparisons. In terms of build quality and setting the car up for auto cross. The camaro is FAR superior in those departments. Mustang did not get good in those 2 departments until S550

Owning both. A lightly modded L99 and a lightly modded 15. The Coyote is slightly quicker. I ran 12.3 vs. 11.9 with equal mods. But I have a Lund tune on the 5.0 which I believe to be better than the SCT tuner.

My guess is weight, suspension, gearing, and a 7k RPM range is the magic combination for the 5.0

wish ford would just add a factory LS motor option

The Ls3 isnt beating an l99 down the track stock vs stock. And its not a drivers race between m6 cars. The 5.0 is quicker. 355 gears still have the 5.0 out front.

I certainly agree that the 5.0 is going to win stock for stock but you say that an LS3 wont beat an L99 stock for stock? I'm kinda surprised at that. While Ive not had any personal experience with that(yet), I would have thought that the additional weight, lower gears and less power would have put the L99 at a dis-advantage...again, stock for stock. With mods I would think that would begin to change.

[gmcvt]

Correct me if im wrong but based on times slips that I'm seeing, the A6 5.0's with converters and tires are running 7.50s as an average in the 1/8. With no engine mods.

The 3.91 rear was the best change I made to my car.

I agree the L99 is usually going to win a 1/4 mile drag race. Hard to out launch or outshift an automatic.
