SLP’s all-new ZL427 Gen IV LS7-based aluminum supercharged long block engine package builds on the phenomenal success of SLP's original ZL402 long-blocks. This engine assembly uses the same race proven internals as SLP's long-block predecessor but now features a LS7 427 block and a Positive Displacement SLP TVS 2300 Supercharger.
SLP's ZL427 engine is built around a new GM LS7 7.0L block, a 4.00" stroke SLP/Manley 4340 forged steel crank, 4.125" 2618 forged SLP/Manley aluminum pistons and 4340 forged SLP/Manley H-Beam Rods. SLP's 1.85 rocker-arm package, SLP 51018 camshaft and LS3 cylinder head combination round out the internals, while SLP's Long-Tube Header Package (required and sold separately) and Custom Tuning are the perfect complements in achieving the ultimate high-horsepower supercharged engine package!
You won't find a higher quality, better value LS7 anywhere!
