The majority of Mast's work has been on GM's L92, 6.2-liter engines. Mast likes these engines for their aggressive head design, VVT feature, and most of all, their affordability. The L92's main application from General Motors is in trucks and SUVs. Mast has outfitted these engines to fit both trucks and cars. The car version uses an L76 intake manifold, while the truck version employs the truck intake (TI). By merely adding the Mast Motorsports V2 camshaft, Comp valve springs (#918), and M-90 ECM with Mast's tune, horsepower numbers have been proven in the 540 range with 490 lb-ft of torque. Not bad compared to an LS7 7.0-liter crate engine, which checks in at 505 hp and 470 lb-ft of torque from the factory. The complete L92 HO V2 turnkey package costs around $11,199, significantly less than the LS7 crate engine containing no electronics.
