PRICE DOES NOT INCLUDE HEADERS AND ACCESSORY DRIVE SHOWN IN PHOTOS

This is a lot of power for the money! We kept costs down using seasoned GM block and heads that we have redone from top to bottom on our CNC machines and upgraded with P1 Manufacturing head and main studs. Extraordinary performance at a great price is delivered by our integrating outstanding parts with our precision machining, assembly and dyno tuning.

The crank we use is a stock-stroke, forged Callies Compstar with 8 counterweights. The additional counterweights increase overall stiffness by about 25% and reduce harmonics so that the crank does not want to flex as much. Bottom line is that the engine lives longer because crank bending and twisting under heavy load is minimized. The forged rods are Callies Compstar Extremes. These are topped with Diamond R series dish pistons. A GM F-Body baffled oil pan is standard. Holley retrofit pans and Dailey dry sump oiling systems are available.

The top-end features seasoned GM LS3 heads that we port our 5-axis CNC. We also machine the combustion chamber to optimize for boost. The valve job and bowl blending is done on our Newen CNC. The heads are assembled with our custom hardware and COMP BSR shaft rockers for maximum valve train stability. A custom COMP hydraulic roller cam brings performance and durability without the maintenance hassle of frequent valve lash adjustment with a mechical cam.

We can build this engine with a range of intake manifolds and intercoolers. The default choice is a Holley Lo-Ram with a 417 Motorsports 1,500 hp rated liquid-to-air intercooler.  We like this system because it is compact, effective and easy to install. A Holley Hi-Ram intake and 417 Motoresports 2,000 hp rated intercooler is a great upgrade if vertical clearance is available. 

Cooling capacity can be further enhanced with an FI Interchiller which uses the AC compressor to refrigerate the intercooler system. Other alternatives are using an air-to-air intercooler or running E-85 exclusively and eliminate the intercooler system entirely thanks to ethanol's evaporative cooling. Regardless of how you do it, holding the intake air temps down is critical.  Water-methanol injection is a great supplemental means of keeping IATs down.

That brings us to the patented, top-shelf, Bulleye 76mm NLX turbo with its all-ball-bearing design which speeds up spooling. Since no center nut is required, the NLX has a three dimensional compressor wheel with greatly increased vane area allowing it to capture more air. The NLX also has an adjustable MAP grove for easy turbo tuning. Check out the video we shot at Bullseye to get more info on these amazing turbos.

Headers are not included but can be ordered along with the required Turbo-Smart hardware.

A Holley Terminator X engine management system runs the whole show with flawless precision. Your engine will be delivered to you with the tune from your dyno session already installed. The optional Terminator X-Max will also act as a trans controller. Either can be paired with an optional Holley Digital Dash to solve all your instrument issues.

Want to customize the look or performance of your engine? No problem. A range of serpentine systems are available and there are lots of personalizing touches we can add.
