Edelbrock 46125 Gen III 426 HEMI E-Force Supercharged Crate Engine

Description

Crank out massive supercharged HEMI torque using the Edelbrock 46125 Crate Engine. Displacing 7.0 liters across 426 cubic inches of Gen III Chrysler architecture, this E-Force supercharged long block produces formidable modern Mopar horsepower. An Eaton TVS 2650 supercharger unit, forged internal components, and CNC ported aluminum heads deliver brutal forced induction power for pro touring conversions.

A heavy duty cast iron Gen III HEMI block features cross bolted main caps to withstand severe supercharger cylinder pressures. The reciprocating kit combines a 4340 forged steel 4.050 inch stroke crankshaft, forged 4340 H-beam connecting rods, and forged aluminum pistons inside 4.090 inch bores. Static compression measures 9.9:1 for 93 octane pump gas. Total long block dry weight with supercharger measures 575 lbs.

Key Features of Edelbrock 46125

Buy Edelbrock 46125 crate engine packages to modernize classic Chrysler muscle cars with turn key supercharged horsepower. The base long block includes the pre fitted Eaton TVS supercharger while allowing builders to select custom electronic control systems and accessory brackets.

• Eaton TVS 2650 rotor assembly generates high volume boost with minimal parasitic drive loss.
• Integrated dual water to air intercoolers decrease intake charge temperatures to prevent detonation.
• Forged 4340 steel crankshaft withstands severe torsional stress from belt driven supercharger boost.
• Forged H-beam connecting rods provide tensile strength under high cylinder combustion loads.
• CNC ported aluminum cylinder heads maximize airflow speed across oversized intake and exhaust valves.
• Hydraulic roller camshaft profile creates sharp valve events without valve float at 6500 RPM.
• Edelbrock 46125 valvetrain parts feature hardened pushrods and matched high load valve springs.

E-Force Supercharged HEMI Dyno Metrics

Testing on water brake engine dynamometers validates extreme horsepower output across a broad 2500 to 6500 RPM band. The hydraulic roller camshaft optimizes intake and exhaust events to expand mid range torque production under boost. The 9.9:1 compression ratio supports knock free operation on 93 octane premium gasoline, while internal galleries maintain 50 to 70 PSI hot oil pressure.

Mopar K Member Drivetrain Integration

Gen III HEMI external dimensions fit into vintage Dodge Charger, Challenger, and Plymouth Barracuda engine bays when paired with conversion motor mounts. The crankshaft couples to modern Torqueflite eight speed automatics or manual transmissions using matched flexplates. The included oil pan clears intermediate steering drag links, while supercharger height requires cowl induction hood clearance.

Supercharger Pre Lube Operating Guardrails

Pressurize the engine oiling channels with a pre lube tank prior to turning the starter key to safeguard crank and cam bearings. This supercharged crate engine is not engineered for marine bilge setups, forced induction boost exceeding twelve PSI on pump fuel, or unmetered nitrous oxide systems.

• Drain break in oil and replace the spin on lube filter after the first 500 operating miles.
• Perform regular motor oil changes every 3000 miles or six months with high zinc synthetic race oil.
• Inspect supercharger drive belt alignment and check intercooler coolant levels every 6000 street miles.
