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 Inconel exhaust valves, dual springs and titanium retainers. The COMP BSR shaft rockers for maximum valve train stability. A custom COMP hydraulic roller cam brings performance and durability without the maintenance hassle of valve lash adjustment associated with mechanical cams.

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. The intercooler comes dressed with a billet water intake manifold as cn be seen in the photoset. We like this system because it is compact, effective and easy to install. A Holley Hi-Ram intake and 417 Motorsports 2,000 hp rated intercooler are great upgrades 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. Effective air-to-air intercooling could eliminate the need for the liquid-to-air intercooler system entirely. Regardless of how you do it, holding the intake air temps down is critical when running gasoline.  Water-methanol injection is another great supplemental means of keeping IATs down.

That brings us to the patented, top-shelf, Bulleye 76mm NLX turbo.  Its all-ball-bearing design eliminates the center nut and speeds up spooling. The patented three dimensional compressor wheel has greatly increased vane area allowing it to capture more air and generate more boost with less heat. 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. Our preferred headers are Stainless Works.

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. FuelTech engine management systems are available as well.

The black anodized billet valve covers are standard. Want to customize the look or performance of your engine? Need a special oil pan? No problem. A range of serpentine systems are available and there are lots of personalizing touches we can add.
