Product Spotlight: BTR PLATINUM LS DUAL SPRING KIT
Alright, gearheads, if you’ve been chasing that extra performance edge for your LS engine, it’s time to step up your game. The BTR Platinum LS Dual Spring Kit – .660 Lift (SK001) from Brian Tooley Racing is the go-to upgrade when you’re running a high-lift cam and want to keep things dialed in tight. Let me tell you, this kit is more than just parts in a box—it’s the insurance policy your high-performance build demands.
G6 Roush Package
Many companies in the automotive industry have developed a reputation for building crazy cars. Companies such as Tein, GReddy and HKS have gained significant media exposure by building vehicles that are outfitted with each company’s signature parts made for their specific project cars. Not only do these vehicles bring excellent exposure to these companies, but they also show the public what creative minds can do with specific vehicles.
PRODUCT SPOTLIGHT: Get Unleashed Acceleration with Soler Performance’s DLX Bluetooth® Throttle Controller
Here’s the deal: if you’re driving a performance car, the last thing you want is factory lag holding you back. You bought it for the thrill, the punch, that raw acceleration that gives you instant gratification. But if you’re tired of stock throttle response getting in the way, The Auto Builder has the answer. We recommend Soler Performance’s DLX Bluetooth Throttle Controller. Your first drive will be mind blowing — it transforms your car into a responsive rocket.

Product Spotlight: Bill Mitchell Products Aluminum LS Engine Block
Lightweight Muscle for Serious Builds
If you’re building an LS engine meant to dominate the strip, carve canyon roads, or simply crush the scales on any dyno, the BMP‑086515 Aluminum LS Engine Block is your ticket. Built from high-strength 357T6 aluminum alloy, it weighs a mere 135 lbs with caps and sleeves, giving you a rock-solid foundation without the ballast of a cast iron block. In short: strength where you need it, weight where you don’t.

Precision Dimensions for Big Performance
The block sports a 9.240″ deck height with 4.115″ cylinder bores and 4.400″ bore centers, perfectly engineered for aggressive builds while maintaining true LS compatibility. Five billet steel main caps, all four-bolt and cross-bolted, keep the crank planted no matter how hard you push. Torque the studs to 75 ft-lbs, the cross bolts to 30 ft-lbs, and you’ve got a bottom end that laughs at high RPMs and boost alike.
Rebuildable and Engineered for Longevity
Each cylinder comes with a replaceable dry ductile steel sleeve, pressed to exact tolerances for maximum durability. Builders can safely bore up to 4.165″, opening the door to serious displacement upgrades. And with priority main oiling and dry-sump provisions, this block ensures your engine gets the lubrication it demands under even the harshest conditions. Screw-in freeze plugs, cam plug, all dowel pins, and pipe plugs come included—this block is ready to go straight from the box to your build.
Built for Builders
Every detail of the BMP‑086515 is designed with the engine builder in mind. Standard GM LS bearings, camshaft placement, and lifter bores make assembly predictable, while the block’s LSX head bolt pattern and drilled-and-tapped motor mounts give you flexibility for retrofits or high-performance swaps. From oil passages to bearing alignment, Bill Mitchell has dialed in the details so your build goes smooth and fast.

Why the BMP Aluminum LS Engine Block Stands Out
This isn’t just another LS block—it’s a high-performance weapon. Lightweight, rigid, and engineered for serious horsepower, it’s perfect for boosted monsters, high-revving naturally aspirated screamers, or retro LS swaps into classic rides. If your goal is power, precision, and bulletproof reliability, this block won’t just meet expectations—it will crush them.
