Anything with a Holley EFI system, including Holley Dominator, Holley HP, Holley Terminator X, Holley Terminator X Max, Holley Sniper, and Holley Sniper 2. We've even done boats with Holley EFI installed! We also do GM LS Gen 3 and Gen 4 (1997-2014) engines, whether that's a "LS Swap" or factory engine. We also do muscle cars, drag cars, street rods, hot rods, etc. The majority of our background is in GM vehicles from the 1950s through the 1970s, but we also do other American brands too. Can also adjust carbureted vehicles and tune jetting and acceleration on Holley carburetors.
