We’ve already seen some of the performance offered by the Callaway SC757 package for the Chevrolet C7 Corvette Z06, watching it go for a hot lap at Thompson Speedway, and seeing it hit 202.3 miles per hour at Mojave Magnum. And just recently, MotorWeek had the privilege of putting the SC757 Z06 through its paces.
If you hadn’t realized it yet, the SC757 nomenclature represents the 757 horsepower that Callaway’s performance enhancements yield, with a lucky 777 lb-ft of torque to go with it. MotorWeek notes that the 0-60 time was two-tenths faster than a stock Corvette Z06 with an automatic gearbox. The SC757 also completes the quarter-mile in 10.5 seconds, over half a second quicker than a stock Z06 with a 7-speed manual, which takes 11.2 seconds.
It’s worth noting that completely stock Corvette Z06 modles with the automatic transmission have completed the quarter mile in an even quicker 10.41 seconds. Does this mean that the Callaway SC757 package isn’t worth the $18,000 price tag? That’s on the potential buyer to decide.
Of course, the SC757 package offers more than just speed; standard equipment includes Callaway interior and exterior badging along with a 3-year/36,000-mile warranty. Hit play to see MotorWeek’s review of the SC757 Z06 for yourself, then give us your thoughts on it in the comment section below.

This SC757 Callaway is the most pretty and beautiful C7 ever, especially in white
do the AWD version
$18K for a little over 100hp seems like a waste of $$. Why not just take a Grand Sport and install the Edelbrock Stage 3 Pro-Tuner System #15712 which pushes HP to “862+” for $7K? Heck, you can even purchase complete fully forged internals as well for peace of mind.
There are always those who know the price of everything but the value of nothing.
One reason you don’t buy a GS then tack on a mishmash of aftermarket crap is that you end up with what you started, nothing more, and often less. (Even putting a 15712 part number to the “kit” doesn’t change anything. “Fully forged internals”? Ditto.)
GM selected Callaway some 26+ yrs ago. There’s
this symbiotic relationship going on. They have history–and a warranty. A Callaway Corvette is its own iconic entity. You buy it because that’s what you want to spend 120k+ large on. Not because it has 3 more hp and “forged internals”.
I bought a 2015 Z06 because that’s what I wanted, not the Callaway (or the Hennesey).
Back in ’90 I bought the ZR1, not the Callaway. Each decision was irrespective of the cheapest amount of horsepower I could get for the $.
Twin turbo, supercharged, nitrous AWD, mid-engined Grand Sports to the contrary, there’s a butt for ever seat. Whether the buyer “wastes” his $ is still, at the end of the day, his call. That is my point. Spend your $100k wisely c4ce.
What Greg said. Also, the GS has different suspension and chassis tuning to account for the fact that it has Z06 bodywork but not Z06 power, and different engine tuning to account for higher compression and direct injection. You can’t just “bolt on” a bunch of parts or even change the internals because the rods are forged powdered metal optimized for that application. The market isn’t mature enough yet to know how to adapt to all this new tech, all at once.
As I stated to Greg you need to do the research because superchevy had an article on an LT1 build with Wiseco internals. While there may be differences in the suspension, everything can be adjusted/changed accordingly. There is more out there than you realize, from parts to engine builds to vendors capable and reputable to do the build if need be. I certainly would not spend $18K to gain a little over 100HP on a car costing almost $80K with 650HP already. Maybe you would.
“There are always those who know the price of everything but the value of nothing.”
Nice plagiarized quote from Oscar Wilde but you conveniently omitted the rest.
“And a sentimentalist is a man who sees an absurd value in everything and doesn’t know the market price of any single thing.”
Which would perhaps be you, moneybags. Perhaps, we should say it like this. A financially unconcerned man who sees an absurd value in everything and doesn’t know the market price of any single thing.
“One reason you don’t buy a GS then tack on a mishmash of aftermarket crap is that you end up with what you started, nothing more, and often less. (Even putting a 15712 part number to the “kit” doesn’t change anything. “Fully forged internals”? Ditto.)”
Well, I would suspect SEMA, and ALL of the aftermarket would raise the BS flag on that statement. For that matter, especially Edelbrock and Wiseco/K1 technologies of who’s products I directly speak. You, Sir, speak from ignorance. Need proof? Try a search for LT1 builds (superchevy has a great one for you). Google is your friend to fight ignorance and yes, arrogance, even if economically induced. “You buy it because that’s what you want to spend 120k+ large on.” Proof of your ARROGANCE…sir.
” Spend your $100k wisely c4ce.” Well, considering what you’ve stated, I would seriously have to say the same to you as you have a definitive inability to define value for the $$$ you spend above and beyond the price of a Z06. I truly believe there is a C7 GS with an Edelbrock SC and forged internals ($65K + $7K +$3K forged crank,rods,pistons= $75K) for less than your base MSRP waiting for you, and Youtube, out there. If not, I’m more than happy to be crowd funded to build said vehicle to embarrass you and your Z06.
Oh yeah, spend your petty cash wisely moneybags ’cause nameplates/badges (callaway, hennesey, lingenfelter) may earn you bragging rights at the local car show but they will leave you embarrassed on the street & track, if your Z06 ever sees them…..
I give up–you really proved up here. You a fellow attorney? Your Knife-like logic, verbal command and single-minded focus crushed any chance I might have had of remaking the original point.
But why would you then demonstrate such an open aversion to success? Why the hostility and anger? (“Moneybags”, “ARROGANCE”, “spend petty-cash wisely”,”poser”, etc.)
I apologize for antagonizing you and for plagiarizing Mr. Wilde. (I mistakenly thought his words had been so long in the commonweal that they were legally beyond any actionable plagiarism determination.) The phrase is fairly well known, you see. Sorry, not my modality.
Now, not to dilute your alligence to SEMA, aftermarket speed equipment and u-tube street racers, but I also have a 1969 Austin Traveller with blown VTEC power and AWD (to minimize torque-steer).
As a “poser” (your words), I’d never dream of using this 1800-lb, air-conditioned sleeper to engage in random speed contests with unsuspecting fellow motorists. Please forgive my words from instigating further ill-feelings.
A final question:. What’s a “definitive inability to define…”? Would Mr. Wilde have a reference? I’ve been so embarrassed by the power of your words I’ve decided to divest myself of half my assets.
I’ll sell several vehicles to fund other car enthusiasts so that we all may share–on an equal basis–our love for high performance cars and u-tube videos of Mustangs crashing while leaving Cars and Coffee events. There, I feel so much better and hope you do to.
Your reply truly has me in stitches. If this thread has not already corrected my edits of my previous harshness, then I truly apologize, kind sir, as we are now exchanging hospitable and may I add humorous dialogue, even if it is tongue in cheek and/or sarcastic in nature. Sometimes a quick retort is quicker than hindsight and the editor, be it internal or external. Now, if you truly have the financial intention and divestment to support a, shall we say, investment into an experimental proof of theory such as I have previously disclosed, then perhaps we should discuss further and future opportunities. Yes, a 2017 GS corvette with said Edelbrock SC and internal forgings with of course the appropriate tune, will provide the the absolute result of kicking the @$$ of ANY Z06 with the aforementioned vendors , (hennesey, callaway, lingenfelter) packages for less $$. Us financially challenged commoners must be thrifty after all, lol, if you will humor me. Cars and Coffee sounds delicious but they may not accept the presence of a lowly C4 but hey, I’m looking for an LS swap or maybe an LT4 if you have a spare one…..maybe from your Z06, moneybags, ROFLMAO, with you of course..
Peace out.
Hopefully this sense of “tamed lunacy” finds its way into the C7 ZR1
The deal with Callaway is that they do produce well sorted cars and they have played a significant part in Corvette history. They are the Shelby of Corvettes.
Now what hurts Callaway is that even though some have been raced in the past they have not done so lately. Also they have come out with special editions like this only for a year later for Chevy to trump them in power and handling with their own model.
As for future values etc there may or may not be a place for this cars in the future. The one that may hold the best value is a TT from the early 90’s but even now they are a good buy. But then again the Shelby’s for so long were seen as just a used up race car.
Their numbers are low but their racing heritage is limited.
Right now this is a good buy if you want a well sorted and supported car and can not build it yourself. But I also suspect when the coming new high end model comes from Chevy it will match this model.
Also once the C8 comes this one will be forgotten like past recent Callaway cars.
To be fair to Callaway they can afford to sell few cars as they only need to sell a few to make money and there are usually enough who have the means to get something ready made like this.
I personally would wait for the Chevy model but there are some who can not wait. That is all up to them.
Much like the first ZR1 and Callaway or even some Hennessey cars they all get surpassed or even forgotten.
I have driven a original Callaway back in the day and it was a sweet car at the time as we though Chevy would never surpass this in the age of the C4. But we found we were considerably wrong to underestimate where Chevy would go. I do not Rule GM out on the future anymore on their cars at least till heavier regulations come.
Callaway SC757 Z06 Corvette offers speed, standard equipment including interior and exterior badging. The great Callaway Cars always upholds something unique with Corvette Cars.
