Optima Batteries’ YellowTop batteries are not your basic car battery. Apart from the absorbed glass mat (AGM) distinction, the unique design and technology are what make it the ideal battery for all walks of automotive enthusiasts. So how does it work? Optima Batteries’ six spiral-wound AGM cells are tightly compressed into one sealed case, giving the battery more plate surface, closer plate spacing, and the ability to use high purity lead. The result is an extremely low internal resistance that allows for more power and faster recharges. The spiral design also locks the plates in place, which gives a YellowTop battery a higher resistance to vibration, longer life, and better performance. The main benefits to Optima YellowTop batteries are: up to two times longer life; more than 15 times the vibration resistance; maintenance-free; non-spillable, can be mounted in any position; lower self-discharge (longer shelf/storage life); faster recharging capabilities; and optimal starting power, regardless of temperature. These characteristics make a YellowTop best suited for modern accessory-loaded vehicles with high cranking capabilities.

Bowler Performance Transmissions is proud to announce the release of their new hydraulic clutch pedal conversion for the 1973-1987 Chevrolet/GMC trucks. This new conversion kit allows for anyone with an automatic transmission pedal assembly to easily add a clutch pedal for a manual transmission conversion.

The add-on bracket is designed for a weld-on attachment but can also be bolted in place if welding is not an option. There is also built-in provision for the addition of a clutch safety switch (not included) if desired for applications not able to utilize a neutral safety switch on the transmission being used. The complete pedal conversion includes new clutch pedal, pedal attachment bracket, new brake pedal pad, two rubber pedal pads, and all necessary hardware. Bowler Performance Transmissions also sells an add-on hydraulic master cylinder kit for this conversion kit to allow connection to any hydraulic release bearing.

Performance Distributors’ new Deluxe D.U.I. for street/strip applications encompasses every feature you’d ever want in an ignition system.  Four terrific features are included in one Davis Unified Ignition package. First, the new Cross-Fire Cap allows you to route your plug wires neatly on each cylinder bank. You get the same 50,000V D.U.I. Coil and high dwell Dyna-Module as you do with their standard street/strip D.U.I., but with the sleek look of your plug wires being well organized. Second, is the Adjustable Slip Collar.  The unit features a slip collar with 7/8 inch of adjustability. This is great if you’ve decked your heads or milled your block, which changes the distance between where your distributor rests on your intake and where it meshes with your cam gear. This will ensure a precise installation, while preventing engine damage from the distributor being out of alignment. Third, a Carbon Ultra-Poly composite gear is used. It is compatible with any camshaft! Whether you run a solid, hydraulic, factory roller, or steel billet roller cam, this gear will provide unmatched strength and reliability.  Solves wear problems associated with other gears. And of course, every D.U.I. is calibrated on a distributor machine, providing a super-smooth advance curve. This provides you with instant throttle response and more power. The mechanical advance is coordinated to work in conjunction with the vacuum advance, preventing engine damaging detonation.
