C7 Grand Sport NA Build: +135 WHP! Stage 3 Heads & Cam (E85 vs 93 Octane) LMR

A clean 2017 Corvette Grand Sport shipped in from Florida… and it left with a completely different personality. In this video, we take you through our Stage 3 Naturally Aspirated package C7 — built for more power, better sound, and an all-around more exciting driving experience. This isn’t just numbers on paper either… this car delivered real gains to the rear wheels 👇 Baseline: 385 WHP 93 Octane: 494 WHP (+110 WHP) E85: 520 WHP (+135 WHP) That’s right — over 135 wheel horsepower gained from a fully built NA setup… while still maintaining smooth drivability and stock-like manners. What’s included in this build: Full CNC ported cylinder heads Custom Stage 3 camshaft (stock converter friendly) Upgraded valvetrain (springs, lifters, trays, etc.) MSD intake manifold Cold air intake American Racing long tube headers + X-pipe ATI balancer upgrade Dual fuel capability (93 octane or E85) The result? A car that idles with a clean chop, pulls hard through the gears, and can still be driven daily — or even road-tripped back to Florida. And one of the best parts… No switching maps, no headaches — the system automatically adjusts whether you're running pump gas, E85, or a mix of both. - - - -- - - - - - - - -- - - - - - -- - - - - -- - Call us today to discuss your build.
