Josh’s 2018 Chevrolet Camaro ZL1 1LE is in for its first round of work! Up first, Andrew is setting the LT4 up with Stainless Works long-tube headers, JLT Performance cold-air intake system, ZPE GripTec 2.30″ upper supercharger pulley, then she’s hitting the rollers to get dialed in by Vlad via HP Tuners! Stay tuned for results!
Jason’s once all-original 1970 Chevrolet Chevelle SS 396 is now powered by C7 Corvette Z06’s 6.2L supercharged LT4 engine! When Jason brought us his Chevelle, he had some straightforward requirements: modernized performance (and a handful of it), modernized reliability, modernized drivability, and modernized efficiency – four boxes which the LT4 ticks beautifully. So, we got to it!
With the 396 engine removed, we started by fitting the brand new LT4 into the engine compartment & adapted to the existing TK05 transmission, then with the powertrain in place, we brought all the various supporting systems together: electrical & wiring, exhaust (utilizing OEM LT4 catalytic converters), oil cooler, radiator & cooling, supercharger intercooler pump & reservoir, heat exchanger, front drive system, air conditioning, power steering, intake system, fuel tank & fuel system, etc.
Once the mechanical work wrapped in the shop, Charlie strapped her down to the rollers for Vlad to perform a custom calibration via HP Tuners.
The results were exactly what we hoped for: 550.10whp & 606.90lbft! Check out the overlay dyno graph comparing the baseline 396’s output versus the LT4’s output… pretty wild difference!
Overall, a fantastic result that achieved all of Jason’s goals for the project. We’re proud to have been involved with this incredible build!

Michael brought us his pristine LeMans Blue Metallic 2007 Chevrolet Corvette 427 Limited Edition Z06 to address the LS7’s infamous valve drop issues, and also add another ~100whp worth of naturally aspirated power in the process! Up first, John installed a set of CNC ported cylinder heads from Lingenfelter Performance Engineering, custom billet-core camshaft from Cam Motion, push rods from COMP Cams, fasteners from ARP, all new OEM GM gasket, seals, fluids, and timing components (along with a C5R timing chain), with a set of long-tube headers from Stainless Works to top it all off.
After the mechanical work wrapped in the shop, Matt strapped her down to the rollers for Vlad to bring it all together with a custom calibration via HP Tuners. The result is exactly what we were after, coming in at 545.06whp & 512.92lbft! Up next, a ported MSD Atomic intake manifold, Nick Williams 102mm throttle body, and a VaraRam intake to let this LS7 breathe a bit easier. Keep an eye out for more to come from this C6Z in the future!

It goes without saying that the 650hp/650lbft LT4 engine found in the C7 Corvette Z06, Gen-VI Camaro ZL1, and V3 Cadillac CTS-V is an absolute beast of a power plant. The only drawback? The OEM supercharger is on the smaller size (1.76L), and is already rather highly spun from the factory (~20,000rpm). While there is definitely performance to be had by modifying the factory supercharger (pullies, porting, etc.), there’s a far more direct path to 700whp+… direct-fitment 2.9L twin-screw from Whipple Superchargers!
And this is exactly what this customer brought his 2017 Chevrolet Camaro ZL1 in for! The baseline alone at 578.60whp & 568.56lbft through the 10L90E automatic transmission with only a Roto-Fab, LLC intake system was already an impressive starting point, but after the Whipple installation and a custom calibration by Vlad via HP Tuners, this LT4’s output jumped to 700.96whp & 682.72lbft! That’s 122.36whp & 114.16lbft increase!
Long-tube headers and a bit smaller pulley will really set this setup off, but for the time being, we think he should enjoy the new performance. 
After getting set up with an Edelbrock Performance E-Force supercharger, Stainless Works long-tube headers (coated with Cerakote Ceramic Coatings‘ Glacier Titanium ceramic coating, applied by Detective Coating), Sean’s 2017 Chevrolet Corvette Grand Sport hit the rollers to get dialed in by Vlad via HP Tuners!
With the LT1’s factory fuel system limiting our ability to pulley this TVS 2300 down and really let her sing, Vlad extracted the most performance possible from available boost.
The result? An impressive 562.26whp & 564.76lbft, all through the 8L90E automatic transmission! Considering stock C7 Corvette A8s put down around 410-415whp/lbft on our dyno, that’s an increase of ~150whp/lbft over stock!
One question we get regularly: is Flex Fuel worth it on naturally aspirated vehicles? Zachary’s 2016 Chevrolet Camaro SS is a perfect example to answer this question.
After getting set up with a Roto-Fab, LLC intake system, Kooks Headers and Exhaust long-tube headers, Borla Exhaust system, MSD PerformanceAtomic AirForce intake manifold, and Nick Williams 103mm throttle body, Vlad dialed in the LT1 first on 93 octane, netting a healthy 442.27whp & 440.10lbft. Then, after setting up Flex Fuel, draining the tank and refilling with E85, Vlad was able to extract 476.80whp & 456.64 — an increase of 34.53whp & 16.54lbft from fuel & calibration alone!
So, there you have it! Definitely a tangible benefit, even for naturally aspirated vehicles.
Tyrone brought us his ridiculously pristine Daytona Sunset Orange Metallic 2005 Chevrolet Corvette from Maryland for not only more power, but also more visual appeal under the hood! Up first, we brought the MSD Performance Atomic AirForce intake manifold, Halltech Systems, LLC cold-air intake system, and Holley Performance Products valve covers over to Seamus at Concept Colors to have each component perfectly paint matched.
From there, Archer carefully installed each component onto the LS2 engine, then she went over to Vlad to get dialed in on the dyno via HP Tuners. Through the automatic transmission, Vlad was able to extra 403.22whp and 402.69lbft! Pretty strong numbers for the modifications performed, considering that stock LS2/automatic C6s normally baseline around 335whp/335lbft. Definitely a difference that Tyrone will notice, both from behind the wheel, and under the hood.
In case you were wondering what rolling perfection looks like…
This is Paul’s 1967 Chevrolet Camaro, and as you can see, all-original integrity wasn’t exactly a priority for its frame-up restoration. Built LS7, full Detroit Speed front & rear suspension, 9.00″ rear end, all made lighter via select carbon fiber panel replacement. It goes without saying, this car is an absolute dream machine, and to us, is the definition of a perfectly executed Gen-I Camaro.
This round, we installed an MSD Performance Atomic intake, paired with Fore Innovations, LLC fuel rails, along with some minor custom fabrication to retain the coil relocation, and now she’s hitting the rollers to get dialed in viaHP Tuners! Stay tuned for results!
Bob’s 1963 Chevrolet Corvette is in for some attention from John! Up first, John has the 327 on a stand for inspection, gasket & seal refresh, and to install camshaft and valve train components from COMP Cams & Crane Cams — on the way back in, he’s fitting a plethora of OEM specification components, including clutch & flywheel, clutch control components, driveshaft U-joints, and an array of miscellaneous components. Then, Vlad is calibrating the Holley Performance Products 650cfm carburetor for the new setup to bring it all together!
