The C8 Chevy Corvette boasts numerous engine choices: The 6.2-liter LT2 found in earlier Stingrays, the 6.7-liter LS6 in the latest models, and the high-revving, 5.5-liter LT6 in the Z06. Electrified versions of the first two power the all-wheel-drive E-Ray and Grand Sport X, respectively, while a twin-turbo variant of the third (dubbed LT7) powers the ZR1. Ultimately, a battery-assisted variant of that engine pushes the 1,250-hp ZR1X.
But what if an 8.1-liter big-block piques your interest instead?
Your only option is to construct one yourself, and that’s exactly what Larry Hofer from Raylar Engineering has accomplished. He literally authored the book on 8.1-liter performance, making it only fitting that he fit one in the center of a C8. It’s been a passion project—one we’ve reported on several times here. But now, it’s finally hitting the streets.
Hofer isn’t out there peeling rubber and executing highway pulls at triple digits in his Corvette just yet. Instead, he’s assessing it at standard freeway speeds to see how it functions overall. This marks a significant milestone for the project, given that no one else has attempted something as ambitious on this platform.
The 8.1-liter C8 successfully completed a relatively uneventful test loop, facing only minor issues that Hofer is addressing. Onboard diagnostics indicated some misfires, although they were never substantial enough to cause serious hesitation during acceleration. A sensor also erroneously detects that the frunk is always open, even when it’s not. However, none of this prevented the car from cruising up and down the road, even occasionally edging close to 90 miles per hour.
While these engines are typically found in pickup trucks, Hofer has made significant modifications. It now includes direct injection and variable valve timing, and soon, it’ll feature a custom intake with individual throttle bodies. The overall concept is to merge the advantages of substantial displacement with modern engine technology, culminating in impressive responsiveness and effortless drivability. It’s nearly silent when the car is cruising.
First 8.1L Big Block C8 Corvette Finally Hits the Road! -May 2026 Update
As per the latest video on Greg Quirin’s YouTube channel, the car is roughly 95% finished. Once they resolve the misfires, refine the idle, and sort out the frunk chime, Hofer will likely have a successful hot rod in his possession. What an achievement.
