Holley/MSD is pleased to announce the release of Sniper EFI systems for Quadrajet applications, which eliminates the need to continually rebuild 50-plus-year-old carburetors on classic Chevys. Able to support up to 500 naturally aspirated horsepower with four 100-lb/hr injectors, it’s the first bolt-on spreadbore throttle body electronic fuel-injection system that doesn’t require additional adapters, sealing plates, or intake manifold swaps.

Spring Into Action
Detroit Speed, Inc. introduces their new Coilover Shock Helper Spring Kit designed to improve shock function. This kit is intended for use when you are lowering your vehicle well beyond the factory ride height and installs over the shock with the primary coilover spring. The helper spring prevents the coilover spring from losing its pre-load when the suspension is in full droop, the shocks at full extension. For more information on these easy-to-install kits go to detroitspeed.com or call 704.662.3272.
MSD standalone Air/Fuel Wideband 02 Gauge Kits are extremely accurate and compatible with both EFI and carbureted fuel systems. Available in black- and white-face versions, these feature-packed, analog-style standalone gauges measure 2 1/16-inch in a slim-style package that takes up very little dash space. Their easy-to-read analog dial includes a 270-degree sweep pointer from 6 o’clock to 3 o’clock. An internal microprocessor controls pointer movement to ensure accurate reading in street, off-road, and race conditions. Check out holley.com or call 866.464.6553 for more information.
Chassisworks adds to their growing selection of chassis accessories a top-quality, billet aluminum vent canister system for gas tanks, rearends, and transmissions. The black-anodized canister and base assembly measures a compact 2.5 inches in diameter and 5 inches long and can be neatly surface-mounted inside the trunk with the vent exposed outside the vehicle or bracket-mounted inside or outside the vehicle.

If you’re going through the time and effort to do a cam swap, you’re going to want to see a pretty big performance gain. That’s why Summit Racing went straight to Stage 2 camshafts. These cams have more lift and trade a little bottom-end torque for more power in the mid and upper rpm ranges. The Stage 2 and 3 cams are rated to 0.600 inches of valve lift with a 1.7:1 ratio rocker arm. The Stage 4 cams are good up to 0.625 inches of valve lift with the same rocker and are designed for big power increases in street/strip cars using a factory-style intake manifold. You’ll find more information at summitracing.com or by calling 800.230.3030.
