And weights 100lbs more than the Mustang engine.

The LS7 has 505 HP @ 6200 RPM's..redline at 7000 RPM's....high revving ability?..i'd say so....
475 Ft Lbs of torque @ 4800 RPM's

Torque is a BIG advantage in the track..mainly when coming out of a slower corner and needing that torque to pull it quickly up to speed...

There is several things that people have been complaining about in the comparison track run they did being called totaly bull..for the fact of the bigger cubic inch displacement..the carbon fiber brake system and some suspension mods that would not be allowed to run in the track class the Boss 302 is designed and built to run...
And these complaints are even coming from the die hard Chevy fans too that are at least honest in opinions and facts..

They have also failed to mention the HUGE price difference between the Z28 and the Boss 302..again..it would of been a fair match if they would run against a GT500 which is would be in the same class and price vehicle...
And the Boss is 380 torque @ 4500 and redlines 7500 with HP at 444.
On a track, spec #s don't mean as much as the intangibles. Have you ever seen a NASCAR ride drop a cylinder at a road track and burn up the track until the engine blows? Yep, has happened many times! The loss of peak power actually makes the car more capable on tracks like that. Too much torque is worse than not enough.
4 seconds is an *** whipping, straight up. It would be much more interesting if ALL models were track tested under similar conditions on a consistent track.

And did you really expect Chevy to do a heads up in which they lost??? O_o

The LS7 weighs..............yup....444 lbs.......

Here's a guy who bought a crate LS7 and did the math once delivered...

The 100 lbs more you found was most likely the delivered freight weight...

Of course they wouldn't "match" anything up..they are well known for it in their advertising marketing schemes..O_o

Another thing they failed to put in the video..is the camaro they ran in the vid has no sound deadening in it..and alot of interior parts to shave weight,,,

But they ran the Boss 302 as is off the showroom floor....( it is already well known the Z28 they ran would not be even closely allowed to run in the race class the Boss was designed to run in)

It would more interesting if they ran more equaly class matched and priced vehicles..

As far as too much torque in track...false..that would be up to the driver if he used that available torque in an overkill situation....its all up how you USE or ABUSE it..and whats available when you NEED it...

I am more impressed with a 302 getting 444 HP than a 427 getting 505 HP..

71 HP more with a hand built engine with 125 more c.i's than a mass produced factory line engine....

I love the LS line of engines..but they are FAR from the "gods gift to hot rodders" engine line up most people put them out to be...

I grew up around dirt tracks and drag strips..and the general rule of thumb was ALWAYS..
You need HP for the quick run in a 1/4 mile..
You NEED torque in the long turning tracks and short dirt tracks..

I pretty much breathed the 1/4 mile growing up and in my 20's-30's( spent way too much crazy money on them all)
And my father and his best freind ran dirt tracks in delaware and Md..
The long stroke torque always prevailed on the dirt tracks and long tracks..just what i seen personaly..not an internet thing...

I disagree.
Torque is the driving force of a 1/4 mile race and most are settled in the first 100 feet where the superior torque(if planted right) makes a big difference. If you have excess torque on a longer track where it has to be used back and forth it becomes troublesome for any driver. Especially on dirt where traction is so often suspect and changing.
Torque matched to the set up and chassis characteristics will always be superior to just having the most. That is why HP/torque numbers aren't nearly as important as skid pad, weight ratio, and slalom numbers in tests like that.
Only thing impressive to me anymore about engine building is when they do it without any extra 'lungs'. Lol

Lowest weight I found for the Chevy was 458 with variences all the way over the 525 mark.

I think the new mustang front end design derived from this front end...

Notice how close that front end looks..

And i like the hell outta the new SHO taurus..the fuel mileage and power number are impressive and i thik they look more "sporty" now than ever...

I traded my 2010 Mustang GT convertible for a 2013 Jeep Wrangler Sport. I loved the car, very fast stock, but I couldn't leave well enough alone... I had Ford Racing cams, high flow intake and exhaust installed. It ran like a scalded dog, dynoing at 348rwhp. Not too shabby for a little 4.6? I miss the 'Stang, but I've had so much fun with this, my first Jeep that I don't regret the trade. The look of this new Mustang is slowly growing on me. Kinda like mold...
