SpeedFactory Cars is fresh off the flight from Las Vegas, NV. The main purpose of the trip to the SEMA convention was to see what Mopar had up their sleeves. Here is a quick recap of what we found;
426 Gen III High Out HEMI and 426 Ready-to-Run Kits
Mopar also is featuring a more powerful, new crate version of the Gen III 426 HEMI V-8.
The Gen III High Output HEMI engine, with 590 horsepower on tap out of the box, is now available under part number P5156139.
Starting with a lightweight aluminum block that shaves more than 100 lbs. from the cast iron version, the Gen III High Output HEMI is professionally built and includes a stout, balanced lower reciprocating assembly that features a forged steel crankshaft with six bolt mains at 2, 3 and 4, and cross-bolted 4-bolt mains at 1 and 5. H-beam style rods are forged steel and coupled to forged 11:1 compression ratio aluminum pistons. Included is a revised windage tray to provide excellent oil dispersion and prevent oil aeration by the crankshaft.
The valvetrain starts with a more aggressive roller camshaft with .639 intake and .628 exhaust lift and cylinder heads that feature the latest designs for exceptional flow characteristics.
To help stabilize the valvetrain at high engine rpm, tie bars are available. Cast aluminum valve covers and billet fuel rails also are part of the Gen III High Output engine. Designed to run on premium pump gas with a minimum octane rating of 93, the newest HEMI V8 is ideal for off road competition or the latest restoration or resto – mod project.
Mopar also is offering two 426 Ready-to-Run engine control/base calibration kits, one for the High Output engine and one for the existing 426 crate engine.
Kits include a throttle body, engine harness and engine controller with base cal. These kits greatly reduce guess work and gets projects up and rolling. Depending on transmission type, axle ratio, and tire size, some final tuning may be required.
If you know SpeedFactory Cars, this will be the next power plant to bring one of our beasts alive.
