LS1 Edition
In this newsletter, we'll focus on the Chevy LS1/ LS6 engines, and specifically the different types of mounts that we have available for them.
The LS1 shares little other than similar displacement, external dimensions, and rod bearings, with the earlier small-block V8 engines. It is an all-aluminum 5.7 L (346 in³) pushrod engine and was rated between 305 - 350 hp and 335-365 ft·lbf of torque, depending on the application. The version fitted to the Pontiac GTO featured a higher-lift camshaft to produce 350 hp and 365 ft·lbf of torque. Beginning in 2001, the LS1 received the higher-flowing intake (from the LS6), and a smaller camshaft to keep power at the same level; this also allowed GM to remove the exhaust gas recirculation (EGR) system (Camaro/Firebird only; 97-00 Corvette LS1 never used an EGR system). The block is very similar to that of the higher-output LS6; beginning in 2002, some LS1 engines were actually built using the LS6 block instead. The LS1 was on the Ward's 10 Best Engines list for 1998.
The LS6 is a higher-output version of Chevrolet's small-block LS1 engine. It is an all-aluminum 5.7 L (346 in³) pushrod engine. The initial 2001 LS6 produced 385 hp and 385 ft·lbf, but the engine was modified for 2002 through 2004 to produce 405 hp and 400 ft·lbf of torque. The LS6 was originally only used in the high-performance C5 Corvette Z06 model, with the Cadillac CTS V-Series getting the 405 hp engine later. The V-Series used the LS6 for two years; it was replaced with the LS2 in 2006. For 2006, the Z06 replaced the LS6 with the new 7.0L LS7.
The LS6 shares its basic block design with the GM LS1 engine, but other changes were made such as windows cast into the block between cylinders. An improved intake manifold, higher-lift cam, and higher compression ratio boost output compared to the LS1, and a new oiling system is better suited to high lateral acceleration.

Urethane bushed, universal fit.
The WSLS200 is a really clean mount. Take your old frame mounts off, because you won't need them with this kit. It includes everything you need except the engine and a bit of welding rod. Urethane bushings typically transmit more vibration through the frame than the rubber bushed mounts. View the assembly video here! Only $132.96. Includes hardware and bushings. Order Online!
Not digging those good vibrations? Try using the stock GM rubber insulated kit.
Motor mount adapters for Chev LS-1 and LS-6. These 3/8" thick steel plates are precision laser cut to adapt stock, early-style rubber (or urethane) Chev insulators to the LS-1 and LS-6 block. The motor mount insulators are included in the kit price. The complete kit includes the metric hardware. These adapters can be used with Welder Series #C005 frame mounts (sold separately) to position your motor at the required height.
Want to use a stock style insulator, only in urethane instead of rubber?
Bob Hilton of Hilton Motorsports helped us design this adapter plate to use Energy Suspension's stock style GM urethane insulators. This is a neat one because it's a direct fit - take out the original motor, and drop in an LS1 or LS6. You can use the same frame mounts, but you might have to move the transmission mount a wee bit. Bob eats LS1 engines for afternoon break, so he knows them inside and out. Give him a call if you have any LS questions or if you're in the market for a new engine. Part number LS166 actually moves the motor back 1" for less firewall gap.

Thanks for having a look at this email. I appreciate your time. If you would like to be able to drop by your local parts store and pick up Welder Series parts for your frame build, please let them know. Dealer inquiries are encouranged.
